kind of paintbrush group stuck

[denzjos]

If I choose a kind of brush group, I can't activate another kind of group brushes.
If I clic on the grey items on the menu, they do'nt react. There is also a menu on the bottom of the brushes but it is also unclear to me how to use it. 
   

Is it a bug or is there something I miss ? Thank you for your answer in advance.

Windows 10, Gimp 2.10.8

It is because none of the groups contain a sub-group

This is my Gimp 2.10.8 (linux flatpak) and my own defined brushes folder (to save the tortuous default location in the Gimp profile) Only seven brushes, which show when I choose that group tag. Can not add anything else to it until I define another sub-group.

   

I can choose one of the brushes and give it a sub-group-tag leaf  I can now add that to the brush group and it displays only that brush.

   

Worth noting that the keyboard up/down keys toggle between brush and brush, leaf

The basic information is here: https://docs.gimp.org/2.10/en/gimp-tagging.html

Tags all-screwed-up due to injudicious editing? Delete the tags.xml file in the Gimp profile folder. Gimp will make a new default file.
