Not Your Average Software Bug

The engineer said “That can’t happen”.
I haven’t had any more of these alternative reality encounters until today when I discovered a bug in my RV’s Victron equipment, in particular the Victron Touch 50 display.

Aside from the sexual overtones, this work around seems just absurd, like trying to fix a flat tire by turning on the windshield wipers. Nevertheless . . .
After jacking the Current Sense hole several times, I checked the Touch 50 display:
