Horizontal scroll on Magic Mouse 1 not working properly

One-finger swipe left/right to perform horizontal scrolling on the Magic Mouse v. 1 does not work properly in many applications (such as column view in finder, Preview, Text Edit, Word, Photoshop).

If I quit BTT so that it is not running, swiping left/right with one finger on my Magic Mouse performs horizontal scrolling properly.
