P-47D-40 Rocket Release Mode Switch "NEXT" and "PREVIOUS" commands not working

[LeCuvier]

As the title says, the incremental commands do not work. The "NEXT" command sets the switch to OFF and the "PREV" command doesn't do anything.

As a work-around I have bound the "OFF" and "SINGLE" to pushbuttons and those work. But the "NEXT" and "PREVIOUS" commands of the switch are broken.
