mobile iron after relocking and unrooting not working

I unrooted and relocked my nexus 6, but my mobile iron still says it is OS comprismised. I did uninstall supersu, doesn't look to be installed. What else does MDM or mobile iron flag for? I am the admin to our MI box, so I can see what's going on, and can retire/readd at whim. I just don't see what else it's flagging for, it just says OS compromised, like when I was rooted, and unlocked.
