There is not much to go on there, but perhaps it is possible that RSD was there before but was not cleanly removed so remnants are still in the database.
Do also make sure you are using the 188.8.131.52 RSD extension though, this is the minimum version for ePO 5.x
If this really was a failed prior removal of the RSD component you'd best to open a McAfee support call for advice to see if it can be recovered or not.
Just an idea, if anyone comes to this post again: https://kc.mcafee.com/corporate/index?page=content&id=KB69416
We are trying this now and waiting for Support to come back to us.
