Yes I am having the exact same problem. I'm running up to date 64 bit on windows. Just as I'm trying to set up my burn to rendezvous the marker disappears. It only displays the orange marker and not the purple one. Before this problem began when there was only one marker displayed it would be the pink one. I never see this now. The problem has persisted through a few reboots. I am a bit worried that no one has commented on this for nearly a month!
