I found strange behavior when importing ROLES from a database into a model.
I import everything, including all ROLES. Here is a list of them with the designation of the problematic section:

These red-marked ROLES (AKROS2, AKROS3) were also imported to me, even though they were not in the original list (see above) at all:

They were not listed because they are not even in the database:

AKROS2, AKROS3 are in the database only as USERS.
When I do a database comparison I get this strange result:

I wondered what happens if I don't import USERS.
Without USERS, there is much more inequality in other roles by comparison:

What am I doing wrong?
