Here's the export of my gestures.
I'm using El Cap, 10.11. Do you have an older version of the app I could download, maybe a couple versions before? That'd make it easier to tell.
I'll try reseting all settings if not. Can I just backup ~/Library/Preferences/com.hegenberg.BetterTouchTool.plist to restore them? Thanks!
Edit: I just tried reseting all settings, and I made just these two gestures, and I have the same problem. So I'm guessing it's not something to do with gestures or settings...
Click the gear icon next to the gesture (see https://cloudup.com/ctabqsxVy8p)
Click "Show HUD overly when gesture is triggered" and enter what you want it to say (see https://cloudup.com/cnD-F-BZFWU)
