RV50 ATT logs seems to be seeing unknown band LTE

I have an RV50 that has locked up on sending and receiving data a couple of times it is currently connected to ATT as the operator and UMTS with RSSI -56.0RSRP 0.0Ec/Io -3.0RSRQ 0.0

Logs look like seeing some LTE not compatible with radio but both FW’s are the latest, Anyone else seen this. I have multiple other units across multiple states and don’t see this in their logs?
