Swiftpoint Z - MacOS - problems with Click Recognition

I've installed a Swiftpoint Z mouse and I'm trying to assign actions to the extra buttons that this mouse has (there's something like a dozen extra buttons on this mouse), but BTT doesn't seem to recognize any of the additional buttons when I try to assign the buttons to triggers. When I click on the 'Problems with click recognition?' button, it takes me to an error page. Any idea what I can do to get it to recognize all these extra buttons?

Device information:

  • Type of Mac: Macbook Pro
  • macOS version: MacOS 10.14.5
  • BetterTouchTool version: 3.05
