Apple script in touch bar not updating

When used with a modifier key (i.e. Alt key), touch bar widgets (both apple script & shell scripts) are executed only once. I have to restart BTT to force refreshing of results.
This happens only when TouchBar behavior is set to default (in App Specific settings)

This seems to work fine here. Maybe try to check this box? (Sorry the screenshot is from my current development version which is why it looks different, but the checkbox should already be there in the released version)
