MPC Iive 2 Retro

I just got my first MPC, Live 2 Retro edition.

My data dial seems to wiggle a little left to right, is this normal?

I pulled the knob off and it is the shaft that is moving. Everything seems to function just fine, was not sure if this is normal. It is not real bad but since I just got it would rather take care of right away. Thank in advance for any advice.

My data dial (on a MPC One) is also somewhat wiggly/loose (in all directions) but is otherwise working as expected I guess.
