AT+QSCAN returns an RSRP of -300 and higher for LTE if actual value is stronger than -52

When running AT+QSCAN=1,1

The RSRP results jump to -300 and lower if the actual RSRP is stronger than ~-52. This can be seen when the RSRP ramps up to ~-52 and ramps down below ~-52

FIrmware:

Is this expected behavior if the signal is strong? The documentation shows the range to be -140 to -44

Dear @lomanve
Which OS do you use? Windows or Linux?
I will share the tool to capture and check this behavior, thanks in advance.

I use Linux, thank you

Dear @lomanve
I have sent to you via Message, please help to capture log.
It is better to share the picture of the actual RSRP.
