Cannot Restore Configurations on 4.7.x firmware ePMP 1000 GPS units

Hello, I am not able to any Restore Configuration files (whether is is 4.6.x text or binary or 4.7.x text or binary) onto devices that have 4.7.x firmware installed on them. Only tested on APs so far (ePMP 1000 GPS units). Several units tested.

The error is:

Configuration restore failed.
