Disable fadmin in darkrpmodification > settings, then setup your inheritance in order of ranks, for example owner inherits from superadmin, superadmin inherits from admin, admin inherits from mod, mod inherits from user, then on setgroup can target do this user = !%mod, mod = !%admin, admin = !%superadmin, superadmin= !%owner, this is how my ranks are setup but with more ranks and it works fine this way.
To do this go to the groups tab in the ulx menu, and select the group you want to set inheritance and setgroupcantarget for.
