Hi there,
I’ve just made a few tests and figured out what the problem is.
To make a long story short, if you need an auto-tagging rule that is triggered when a file is put into a certain folder AND the file name contains certain letters (e.g. “-07”), then create/edit the auto-tagging rule from Tools > Auto-tagging rules
We’re working to fix the issue of creating the rule while right-clicking on a folder.
