Hi. Thank you, I read this post before posting my own but I made sure to merge instead of delete, and the second option does not apply here as no one else has opened this document and they are not in duplicate libraries. And either way, I'm still unsure how to fix the issue.

Unfortunately, it will not let me copy paste the toggle field. it only copies the citation name (any suggestions?). I will say that if I go through each one and manually update it, the A/B goes away, as does the occasional format of putting the author's initial first (which I don't want). It seems to be an issue when I "refresh" - it reverts back.

Thanks! Here is one exUpdated citation when I manually update w/ctl+z:

Cockerham 2013a was inserted from a library that had never been synced (hence the 'local' in the uri). That might have been on a different computer, or you deleted the item before syncing the local library. If you have a lot of these, export/import would also be a plausible scenario. I can't tell you exactly how that happened, obviously, but it definitely did.

There's currently no alternative to replacing the duplicate citations individually, sorry.

The only reason they don't how up this way when you edit them is that you have automatic updating of citations turned off and that means citations are displayed without respect to any other citations, i.e. no disambiguation etc.)

As I say, no alternative to fixing this individually for each citation that I'm aware of. So you'd replace (remove and re-insert or edit citation, delete the citation in the dialog and reselect) every instance of the 2013a version, making sure you insert from "My Library" and not from "Cited" (if you're using the red quick format insert citation; the classic dialog will insert from My Library automatically).
