Panasonic Leica 100-400 ticking noise with single shot mode

Hi all. I've just bought this lens (Panasonic Leica 100-400) and while testing found one very weird problem(?). When shooting in single shot mode after every shot lens produces some clicking noise and you can even see that stabilised part of the lens is wabbling or shaking every time you press shutter button. I shoot wide open so it's not an aperture. It's totally silent with ois disabled or in multiple shots modes. It's also silent with Olympus OMD e-m5 II, but clicking with Panasonic g80/85. Also found that this behavior depends on angle you keep your lens on.
Does anyone else have the same behavior?
P.s. camera is g9 if it matters

Haven't noticed that on mine (100-400 + G85 and GX7).
