My AirPods pro 2nd Gen shows different model numbers for left and right buds, Are they legit ?

I recently ordered AirPods pro 2nd generation (USB-C) from flipkart, Like, there is a model number for that inside the case Model A2968 and on Ear Buds have different model number Left Ear Bud A3048 & Right Ear Bud A3047 is it original or not and also in Bluetooth Settings Model Number showing like A3048 After some time A3047. I'm a bit confused plus I'm very doubtful if it's original. Please clarify my points
