Note:
Before bug reporting, please make sure you have tried the latest (alpha) version of BetterTouchTool
→ If I click it, nothing happens, even none happens in the extended display, so I’m not sure it’s the LATEST (alpha) version. But this bug report will matter for BTT, so plz read, it’ll be short.
and that you have already tried to restart your system 
→ I’m in my flow of work, so I can’t restart now, but this report is still valid because it has happened far before, I’ve encountered this symptom whenever I use the extended display mode.
If you encounter a crash
→ Nope.
Describe the bug
When using some extended displays, new BTT's popup-window locates on else of the main display. I think it’s not a bug of soley BTT, because if I click System Settings it sometimes pops up on the extended display.
Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
I guess it doesn’t matter, but I used a common mouse, not Magic Mouse.
