It might be a bug in JP2 (which is an alpha quality firmware), which might not be reading the imei properly. I'm pretty sure that the imei has to be basically be burnt into the hardware these days (so it can't be changed). It's possible you see the incorrect imei but your mobile carrier doesn't.
On mine, I've tried JF4, JG1, JG5, JP2 and now back in JG5 and imei is fine.
If your imei isn't correct (double check with your box), downgrade the firmware first. But tbh, I don't think this is actually possible...
