Hi Bill, I am still working on an answer for this question... Just wanted to give you an update!
Unfortunately there isn't a way to override this. We prefer to get this information directly from the device as it is critical to the system. A temporary work around is to edit the devices in question and add this information to the Friendly Name field. It will not solve the problem, but it will allow you to include that information in Beacon.
Meanwhile, we are going to have a link very soon for our Model Data Improvement Program. I am going to submit this information ASAP for you. For any future issues like this, please keep an eye out for this button on the Beacon Forum homepage.
I apologize for the inconvenience.
