epdm why are all my files read only?

Not sure what happened but all our files are read only after checking in. I turned off read only on all files but they went right back to read only. We've looked at Solidworks nothing, can't find anywhere in EPDM that would cause this. So went to copy tree that isn't working either. Not sure what is going on and how to fix issue.

Please help,

Thanks Renee
