iOS ABRP V4.3.3 (2014)

I have two saved vehicles, but I can no longer change the vehicle on the CarPlay display. (Screenshot #1)

With iOS ABRP V4.3.3 (1995) it was still possible to choose between the stored vehicles at this point. (Screenshot #2)

ABRP v4.3.5

Sometimes I see the issue and sometimes not. Strange.
