Touch Bar control strip buttons still show after shortcut keys released

Describe the bug
I have a couple Touch Bar control strip buttons setup to only show when I have certain keys held down. But they often continue to show up even after those keyboard shortcuts are released. Even if they don't show visually, the default BetterTouchTool control strip button will do whatever action they've been assigned.

Affected input device: Touch Bar
