Remove entries in mcexecstate 1536

HI All,

IDM 8, SP7

I am trying to remove pending role assignments.i tried to do that through cancellation of Approvals ids via uis_aprpoval. But teh role entry went to mcexecstate 1536. Now i have tried to remove these through UI. But the pending role assignment does not get removed.

Could you please suggest how to resolve this

Regards
