At the moment, if you turn off both practice directions with (all shortcuts are given using defaults) ctrl+alt+f, pressing either of the toggle practice backward (ctrl+shift+g) or forward (ctrl+shift+f) shortcuts on the same rem does absolutely nothing. In contrast, if you manually turn off both directions, you can turn them back on one by one. See video.
I assume this has something to do with “Toggle practice” doing more than is needed. A slapdash fix would be to just make it toggle both directions off simultaneously using the logic of those buttons rather than whatever it’s doing currently.
