Subgroup option is not avalible

Subgroup option is not avalible

Hello
I have two Password Manager Pro instances. One old (kept just for backup) version 9.3.0.
The other one is newest (i believe) version 12.3.0
And my issue is that on the old one I can create Subgroups, but on the newest one this option is missing completely  
I have searched settings but haven't found anything related to it.
Was this feature removed in some version in the past or Im missing something here ?
