@3gg5amp1e This may be a feature request instead - I don't see anything documented on WP:AWB/GF stating that AWB removes duplicate tags.

@GoingBatty: it seems really silly that it wouldn't since I've seen it reorder tags and put them inside of Multiple issues when there is already a multiple issues on the page (although I haven't seen it wrap multiple tags in multiple issues on its own or remove multiple issues template when there is only one issue, which it should probably do too.). Anyways, if you think it should be a request, please do move it for me as I'm not sure how to do that exactly or what the protocol is. Thank you very much @GoingBatty.

The example article has two {{tl|orphan}} templates with different parameters. I don't think we should arbitrarily be removing one of the duplicates.

@3gg5amp1e: Do you have a suggestion for non-arbitary logic that could be used to remove one of the duplicates? GoingBatty (talk)

@GoingBatty date= should always be the older one and additional tags (like att= in this case) should always be the newest one. date is when it started being an issue, and the oldest is appropriate, other parameters (at least in the case of Orphan with att and few) and the most recent attempt is always the most appropriate.

https://en.wikipedia.org/wiki/User_talk:Addshore#.28Bot:_Adding_.7B.7BMultiple_issues.7D.7D_.7B.7BOrphan.7D.7D_.28Report_Errors.29.29 addbot may have been the cause of all of the duplicates being added in the first place, if it is of any importance.

I'll copy my reply on my talk page to here for convenience:

Thanks for bringing this to my attention! This isn't something I remember fixing or ever being mentioned before so I can only presume that it has not been spotted until now (had a quick search in my talk page archive and couldn't find anything.
As it was so long ago I can't remember exactly what script was used to make the changes. I don't remember ever adding general fixes such as white space fixes to my custom PHP scripts so the diffs almost make me feel like this was AWB O_o (I could be wrong however).
If we want a list of articles where this might have happened I could probably generate one with a DB query, If you feel I should fix the errors I would also be more than willing to do so!
Added myself to the phab task so I can follow it ·addshore· talk to me! 19:22, 15 June 2015 (UTC)

The query / list I mention should be visible at http://quarry.wmflabs.org/query/3989 once it runs!
Failed to run above as it takes so long, so here is a temp dump of the output http://tools.wmflabs.org/addshore-dev/addbotOrphanDupeFail.txt

The list above shows addbot's edit - some of which were correct, and some of which already fixed. I did a regex singleline search in the recent database dump for "{{Orphan.*{{Orphan" and found 100 articles, which I'm now fixing manually. Note that many of the issues were NOT caused by Addbot.

I support the logic that @3gg5amp1e provided above. Please note that there are other tags that are duplicated in the zeroth section of the article, such as {{unreferenced}}. An easier example is [[Nord Nord Ost]], where the two {{unreferenced}} tags have the same date. Interestingly, AWB doesn't add the {{multiple issues}} template in this case.

rev 11181, exactly identical maintenance tags will be deduplicated (so satisfies the [[Nord Nord Ost]] test case).

Confirmed - thanks!

Can we close this as resolved?

Please don't close it yet, as we haven't resolved the original issue.

Confirmed - thanks for making these updates!
I see you've added these updates to AWB's history page. Should they be added to the general fixes page too?
Thanks!

@GoingBatty Feel free to update the manual.

@Magioladitis - Sure, but which section of WP:AWB/GF? Tagger, or somewhere else?

@Rjwilmsi I am only requesting that {{one source}} be added to the list. Thanks!

The new functionality doesn't keep the {{Notability}} parameter from the oldest template - see [[Steve Malpass]] and [[See Monkey Songs]]

Confirmed - thanks for all your work on this!
