Hello

currently I am evaluating PMP.
I have a resource group based on matching criteria.
When editing the group and clicking "search" there are several resources listed - so the filter/criteria seem to work. 
When editing one of the users listed there I can see that the user is not automatically added to this group - I have to add this user manually to this group. Even whe creating a new user that matches the criteria this user is not automatically added to this group.

What am I doing wrong?
