Keycloak 18 display issue (HELP)

Hello all.
I attributed a client role to a whole group - each member of that group can successfully access the client with that role and each member of that group has that role as Effective Role in each member profile

HOWEVER

when I get to Users in Role on the CLIENTS tab → Roles → Users in role

NONE of the group members are listed ( there is only 1 single test user in the list that does not belong to that group and was added manually)

Thanks a lot for any insights
