Roccat Kone Pro Air creaking

I have this mouse and I really like it. I am close to keeping it over the Deathadder V2 Pro.

However, I have some creaking when I squeeze the mouse with a pretty normal amount of pressure. The right side seems to be where most of the noise is coming from.

Does anyone else have this same issue? This is my first time using a super light mouse, so I am not sure if some creaking is to be expected.
