different model number on airpods pro

hi

i recently bought airpods pro 2 with magsafe type c. the problem is that on the box model number is written A2931 A3048. the model number A3048 is also written on magsafe but on airpods themselves the model number is A2698. i checked apple website and found out that A2698 is the lightning version not type c. the whole device works ok.i check the serial number written on the box and in settings which are the same with apple coverage site it says it's genuine and has warranty.

below the airpods model number a serial is written which i don't know what that is because it's a different number.

but i don't get why there's 3 different model numbers!?. is this fake!?

and will i encounter any problems if its original but there not as it should originally be. i couldn't update the firmware.the firmware in settings is 6A305 and i couldn't update it.is there a way to update ?do i miss anything if i have the lightning version of airpods and type c version of magsafe?

i mean performance wise and software. i would really appreciate your thoughts.
