I've said this in a private message already but in case anyone with this issue happens by...
When the collection is set to moderated posting, the fic with the issue hasn't been approved, and a writer tries to update their own fic, AO3 sometimes seems to think the fic is still being posted for the wrong exchange as well as the right one and keeps the box for that assignment checked even though the writer literally just unchecked it.
If this happens, the writer can't fix it but the mod can. If you reject the fic from the moderation queue, that removes it (but it might add back in on subsequent edits and the writer wouldn't necessarily know it ever happened if they're not told, plus it's messy because you can't be 100% sure it's not meant for that exchange and is just mistagged), or you can approve the fic and then get the writer to remove the wrong collection themselves.
I've submitted yet another support request but it's unlike to be fixed anytime soon.
