Can't Remove Favourites (macOS)

[BLUEFROG]

This was already discussed here…

Item in Favorites keeps reappearing

It seems the issue is related to that specific document. To troubleshoot, I tried adding a few other documents from the same database — and also from another database — to Favorites. Then, one by one, I: Removed each item from Favorites, Closed and relaunched DEVONthink after each removal. All other removed Favorites stay removed after restarting the app — except for that one

However, we have not been able to reproduce the issue so far.
