Inconsistencies during role update

Hello Gurus,

Scenario: When custom tcodes are added to an existing role and the profile re-generated, the change documents shows deletion of some other Auth Objs from the same role.

We found that, upon the addition of the custom tcode, ACTVT 01 was removed from one of the Auth Objs and the chnage documents were showing that some other standard Auth Objs has also been deleted.

Can anyone provide some insight on this scenario.

Please note that just for testing purpose, we had created a test role by copying from any existing role, here too the chnage documents showing deletion of some Auth objs.

Is this a problem, with the Change Documents , which are being displayed here. Also, would like to re-confirm if manually added ACTVT gets overwritten if a new tcode is added to the existing role.

Regards
