PO release - Wrong agent assignment issue

Hello friends,

i have a strange issue with PO release strategy . A particular PO has been assigned to release group EG and release code F2 .

But F2 has no agent assignment defined . However , The PO approval is going for another agent belonging to release code F1 . there are no user exist or BADI defined .

Please assist me what could be the issue ? i do not have debug access and the data is not consistent on test system .

thanks
