BTT Disappears from Login Items

Describe the bug
Whenever BetterTouchTool updates, it disappears from my user's login items. Next time my computer restarts, I have to open BTT manually.

Device information:

  • Type of Mac: MacBook Pro (Retina, 13-inch, Early 2015)
  • macOS version: 10.12.6 (16G1408)
  • BetterTouchTool version: 2.513 (850)

Please see Is it just me – or does each update of BTT force me to re-add it to the Login Items under Users?
