Help: plastic shavings in and around piston

Hey folks,

I've opened the gearbox on a G&P TR (v2 gearbox) to change the spring today, and noticed a lot of plastic shavings in and around the piston. Upon closer inspection, it seems like the spring is taking away plastic around the rim of the plastic piston on the inner side, where the spring first enters the piston.

Question, is this "normal wear and tear" or is something seriously wrong? If something is wrong, could you provide some details on how to fix this issue? Or what could be the potential cause?

Thanks in advance!
