Mikrotik powerbox pro System voltage not reporting

We have several RB960PGS(Hex Poes) that properly report system voltage, and just deployed an RB960PGS-PB(powerbox pro - hex poe in outdoor case) however libre doesn’t seem to pull the system voltage. The OID is the same as the RB960PGS(which it does pull), and I can do an snmp get for that OID and get the expected value. Do you have any suggestions on where to look for this?
