User Interface does not save (anymore?)

Hi, 
I am currently trying to create a global UI and Settings for our company.

Therefore i created a new profile and also a new ribbon tab.


Somehow it keeps deleting some ribbon tabs that I've added to our company-ribbon-ui when I restart DS (2021)

The elements in the UI, such as G-Code-Generator are disabled in the UI but are there again when restarting the program.


Do I miss any settiings that prevents my custom UI from accepting any further changes?


Thanks in advance


Sincerely

Christoph
