Better touch tool overrides Command w

I have tried the latest alpha version

Describe the bug
When Better Touch Tool is running and I open the Mac calendar app, the app doesn't quit with "Command + W" like it should do. When Better Touch Tool is not running, I can normally close the calendar app with "Command + W". Same happens for der Apple PDF reader from my Mac (I think its called "preview" in English).

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):

Device information:

  • Type of Mac: MacBook Pro 2020 13.3
  • macOS version: Catalina 10.15.7
  • BetterTouchTool version: 3.558 Alpha, but I have also tried it with the latest stable.
