I have a recurring problem with Zotero displaying incorrect sub-items when I expand an entry. Sometimes, I see other top-level items listed as sub-items, and these can have still others nested under them. If I collapse and re-expand something, a totally different item can appear. There is consistent trigger or pattern to it that I can see, and the only way I know to fix it is to restart Firefox. It does not appear to have actually corrupted any data, since I know better than to keep working when it starts up, but it is very confusing.

I never get an error message, but I have submitted a report: ID 2049415951.

Thank you!
