EPDM label and history

Hello,

I am trying to edit the labels under the history of some pdf files. EPDM is allowing to edit the events and transition that were under my name but not allowing me to edit events under someone else name. Does anyone know why I can't do this? I am the admin for EPDM and have full rights and access. I am running EPDM 2014 service pack 2.
