Problem changing security

Hi! I created an app and I wanted not to let certain groups to execute record actions. I changed the security in the process model, so that only admins can be the initiator (same in rest of the objects), but when I eliminate myself from the group admins I still can execute the actions. 

But the fact is that the views of my site in fact work if I change myself from groups. Why aren´t related actions permissions working?
