APN reverts automatically

Hello,

I want to change the APN on my FX30S device using the cm data apn command. I can see the APN is correctly updated when I run cm data info, but as soon as I start the data connection with cm data connect the APN reverts to its previous value.
Is that a known problem? Do I need to do something else to save the new APN value?

My device runs firmware version R15.1.0.004

What is the return of “app status”?

Is it same issue as this one?

app status returns:

It does not look like the same issue in the link you posted. I am using the generic image without octave.
The APN reverts to the one I had set when using a different SIM in this device, about 2 weeks ago.

what are the return of the followings?
