Chaning STAR and APPR removes flight plan

[sk0941]

I've noticed that in 1.0.8 I'm not able o change the STAR or the approach once I've programmed them. If get assigned a different STAR or approach midflight my flightplan will disappear and send me direct to the initial waypoint of the STAR or the approach.

To fix it I've had to reload the flightplan in the MCDU, load in the new arrival and approach and then go direct to the waypoint I was going to before it all disappeared.
