BR1 Pro 5G No 5G connection

Does anyone know why this device would prefer LTE over 5G connection? I don’t know of a way to scan for bands but I can see AT&T has 5G in my area with almost line of sight to tower about a mile perhaps away. Keeps grabbing LTE band 14 which of course has near excellent signal strength and quality according to RSSI, RSRP, RSRQ etc…
