Hi Mudavim ,
Thanks for letting us know about your usecase!
We have managed to find out what's causing the issue and are seeing how we will fix the issue.
The issue is coming from the fact that when you create more than 10 groups, the data being sent to be saved exceeds the max_input_vars in your php.ini, which is 1000 at default.
For a temporary solution to this issue, you can simply increase the max_input_vars in your php.ini.
To test if this works, I increased my max_input_vars into 2000 by adding this into my php.ini:
max_input_vars = 2000
After I increased this value, I was able to make double the groups I was able to make than before.
Let me know if this would work for you!
