Stale Operator ID retrieved by libmm

Hello,

I have mmcli output being monitored and it shows that device is in 50501 network: image

But qmicli nas-get-serving-system shows that modem is in 50502 network: image

MM log shows that MM receives the ff serving system indications during the network switch but it MM does not process the indication correctly:
