@Comfr Only you can see your notifications. Can you create a screenshot image of the problem, and then share that image by dragging it into a comment below?

Probably caused by this change in a navbox: https://en.wikipedia.org/w/index.php?title=Template:Packaging&diff=860763498&oldid=860763072&diffmode=source

I'm not sure if links from templates are supposed to be filtered out?

This is not a screenshot. I copied and pasted from the page into this box.

matmarex, I see what you mean. The template was added, resulting in Flame treatment‬ being added to all those pages.

But why are they showing up, one by one? For example, I got notified September 27 about "Intermediate bulk container," even though the template had been added earlier. https://en.wikipedia.org/w/index.php?title=Intermediate_bulk_container&oldid=857651935

Aklapper renamed this task from Incorrect notifications, such as, "A link was made from ‪Bulk box‬ to ‪Flame treatment‬." to Receiving confusing notifications such as, "A link was made from ‪ABC to ‪XYZ." (after template edit?).Sep 29 2018, 10:12 AM

Even more confusing, the notifications provide a link to "View changes," but the changes have nothing to do with a link to Flame treatment‬.

Here is an example of where I get by clicking on "View changes."

Similar issue reported in 2013, marked as declined: T50547: Echo: Pagelink notifications triggered on template update. I'm afraid it is still unfeasible to improve this behavior.

rECHOa01ebbc045c2: Fix page-linked notifications could be the cause, in particular this remark:

Also remove the code that refused to route events to a page creator if
they didn't have an agent. It's perfectly legitimate for events not to
have an agent, that shouldn't preclude them from using non-agent-related
locators.

Per T205742#4626983, the notifications seem to have no reference to the users...
