Device information:

  • Type of Mac: MBP 15" 2016
  • macOS version: 10.14
  • BetterTouchTool version: 2.717

Additional information (e.g. StackTraces, related issues, screenshots, workarounds, etc.):
Open up calendar and resize it to not full screen. Map any action to "Maximize Window". I use "Three finger swipe up".

Attempt to invoke that action. It works for any window except for the calendar one.
