Having a problem to decode a captured log using monitor-example.py on a Quectel EC25 modem

[fjremnav]

I have a Quectel EC25 modem connected to a linux PC. and am able to use monitor-example.py in mobileinsight to capture logs with this.
However, python3 ./offline-analysis-example.py monitor-example.mi2log to parse it, I got the following output and it seems not right. The log is the attachment for purpose of reproducing this issue.
