SUMMARY
I added some Bundles and created new Tags to organize my huge amount of Brushes. As I created the first new Tag, suddenly doubles of the most old Tags appeared and some of the Brushes of that category were split to both of those doubles, some didn't. Some of the doubled Tags were empty. I chose german Names for my new Tags (don't know if this is important to say), to get a better Overview. Than I assigned the individual brushes to the Tag I wanted. That sometimes caused a horrible and confusing Mess, because suddenly, for example, all my "Aquarell"-Brushes appeared under the "Airbrush"-Tag. It seemed that the Brushes got moved to the next Tag, if I inserted a Tag above them.

After a Restart of Krita now all seems to be as it should be. Only one doubled Tag still remains. And all Brushes I assigned to new Tags are where they should be. But the Process of creating Tags and assigning Bruhes to their new Tags was really chaotic and confusing.

STEPS TO REPRODUCE
1. create a new Tag
2. assign a Brush to the new Tag
3. ...

OBSERVED RESULT
A well organized Brush-Menu so far. but a chaotic way to get it.

EXPECTED RESULT
A well organized Brush-Menu.
