Regarding the engine switches, make sure that the External/Starter Isolation switch is turned on, that is the most typical thing that would prevent the starters from their operation. This system is described on page 2-4 of the manual.
Regarding the external covers, there is a bug preventing their logic from working, this will be fixed ASAP. To hide/show them this can be done through the sidebar menu; if you hover your mouse on the left edge of the screen, the tab to open the menu will show. We will make sure to get this documented in the manual.
