AR mk2 performance knob reeling

Today I noticed that the encoder is unsteady, has anyone encountered such a problem? Is it possible to fix it yourself?

I use the device since January, carefully, I did not drop it and did not transport it.

All of my MnM knobs are like this, as long as it’s not jumping there’s no worries.

I don’t think that’s unusual for Elektron knobs.

Other knobs are fine. On my octatrack mk2 all knobs are fine too.
Perhaps this is typical for older devices or devices that have been used a lot. In the new devices, encoders are more qualitative and I almost did not use this performance knob.
