Hi! Anyone know what the yellow dotted box is around some of the cab names in the cab block? They keep changing without me making any changes. This screen shot has the left most cab highlighted with yellow dotted box (the only one highlighted). When I click the "Cab More..." tab, and then come back to this main tab, then one or more names have the dotted yellow box when I didn't change anything. It seems random. I don't see this described in the manual.
