Mag Switches and Others

Don't know if this is a bug with FSX or me doing something wrong. On the JF Chipmunk, Ant's Tiger Moth and the just released DC3 I save a flight with everything off i.e. Cold and Dark. When I load the saved flight the Mags are on as is the fuel on the Chippy, the Mags are on with the Tiggy and the DC3 the Mags and the Master Ignition are all on. All realism setting are on the hard setting, I tried with Carenado aircraft and they save correctly.
