Chic Case small problem

The aluminum housing for RX100M3 looks very chic and fits well visually to the camera. It is delivered incl. Carabiner (sw) to attach (to what?) And a relatively large cloth bag. So far so good. Inside both sides stiff knobs are mounted, which are to hold the camera. It may happen that the knobs, press the small button on the camera back. By vibration, it is possible that the camera is turned on "Play" and is the 2nd time in the recording mode and tried extending the lens, preventing the closed case. I just had it yet noticed in time and taken the battery from the camera. It would be nice if the manufacturer could make the pocket differently (eg by a soft foam insert with cut-outs for buttons). Since my case like well, I'll keep it and remove the offending pimples themselves.
