Continued from T104707#1444155
Gadget slurpInterwiki.js can add labels together with sitelinks when requested but it could also add labels with anchors (#) when such interwiki links were present in article.
As such labels still exist, I suggest to remove them all and/or find a replacement (eg. from present aliases etc.).
It seems about 1000 items does have anchored labels incorrectly. But fixing it is very tricky and can't be done be bots (e.g. if we remove anything after # it makes a mess and leaves the item in worse situation than it was before)
So I created list of them of put it in google sheet so you can fix them:

So I close this bug as resolved but if you have an idea on fixing labels automatically I would be more than happy to reopen this bug

Thanks for the list. I think that we could reduce the number of labels by excluding those with space before or after '#'. These are certainly false positives.
First idea: strip the first part of the label (before #) if it begins with "List of ", "Seznam ", "Liste der ", "Lijst van ", "Lista över ", "Anexo:" etc.
There are 118 labels like that and we have several false positives like "List of number-one singles in Australia during the 1940s#1940". I'm in favor of fixing them manually or semi-automatically.
