Name set = new complete failire

Connect to fresh RakBoard 5005-O/4631 (BattleFeng Meshtastic Node). Everything works fine until I set my name and US region. Then the BT name changes from Meshtastic_XXXX to (My Initials)_XXXX and my phone will no longer connect until I reset the modem to factory defaults. Unsure what to do. Latest firmware as of today, 7NOV22.
