SEP 12.1.5 can't change scan time on unmanaged client

I updated from 12.1 to 12.1.5. After updating to 12.1.5 all my unmanaged clients can not change the scan time. When right clicking on the scan, both edit and delete are greyed out. When double clicking on the scan an "Access Denied" box pops up which says: "This is a read-only scan - it cannot be edited."

When I had 12.1 all my unmanaged clients could change the scan time with no problem. Am I missing something?
