CS don’t handle bugs, nor do they forward them on. You can file a bug report in game:-
To report a bug in-game:
- Press Esc or click the ? button to open the menu.
- Click Support.
- Click Submit feedback or bug report.
- Enter the details of the bug into the Submit a bug description box, making sure to follow the guidelines outlined on the submission form.
- Click Submit.
You will not receive a response but it will go to the right people.
I can see on the US bug report forum there are mentions of this too, so you are not alone:-
