Colour coded labels have disappeared and Scrivener can't save project

Hi - I opened my latest project this morning and all of the colour coding on my labels has disappeared in the draft. When I look at labels, it implies that they’re still coded, but the folders in the draft are all generically blue… I’m running Catalina 10.15. Has something happened with an update that’s affected labels in Scrivener? I use them all the time to keep track of where I am in my projects so this has completely thrown me!

Oh my God - in the meantime Scrivener has just ‘quit unexpectedly’ twice. The third time I got this message: There was a problem saving the project.Not all recent edits could be saved. Files that could be recovered have been saved to xxx’

This is a big issue. I can’t work on my project. Any suggestions???

I have reinstalled both Scrivener and Dropbox, then restarted, zapping the RAM, and the problem is magically fixed.

Thanks for your reply. I’m wondering if it was a Scrivener update that caused the problem, or a Mac one!
