What makes you think QSYSOPR has changed from a “regular” to a “group” profile? I can’t find any attribute of the profile that would indicated that.
I know you can create a group in the Navigator, but i haven’t really used that extensively. I did create a group to see if it created a profile but it didn’t.
As far as i know, using a profile in the group profile parameter of another profile does not change the profile being used as a group profile in anyway. For example, i have QSECOFR locked down and specify it as the group profile for myself and another person that i want administering the system. If i run the dspusrprf command, QSECOFR has nothing to indicate that it is a “group profile”, it’s merely referenced by the other two.
