Toolbar adds some strange groups, bug?

Hi, I tried adding a separator to my toolbar a few times, but nothing happened, so I just made a button with no command that was named - - - - - - - - - - - - - - - - - and that works fine, but when I was going to save it I was presented with this strange thing:

…some 6 “Groups” with 2 tabs oddity, that I can not remove or delete.

What is this? How can I remove them and can you look into the separator thing too?

@CallumSykes I don’t know if you work on this as well.

separators only work in single row or column setup

The bug you show should be fixed, but I have to dig up if this was only in Rhino 9 or not

edit: yes it was, but caused other issues and was reverted:
RH-81293 Toolbar groups getting duplicated

Can I manually go into the file and fix this? Or do I have to wait for a fix on this one?
Or make another new toolbar and drag all the icons over once again?

Sorry for the frustration, but this entire toolbar mess makes me feel like I am sitting and bugtracking on an early prototype. It is such a waste of time.

fwiw: It’s more a visual bug than anything else, the groups are not actually duplicated.

They seem to have disappeared now too, after a save and a restart of Rhino.
