Re-Starting an incomplete mission

Hi all, I wonder if I’m doing something wrong? I did a flight this morning brought the copter down to swap batteries then attempted to restart my mission, however, each time it would go back to the starting waypoint, rather than continuing from the last point in the flight. Is this normal? I thought it was suppose to pick up where it left off?

When you continued your previous mission, did it prompt you to say whether you wanted to continue or restart the flight?

It showed me the incomplete mission and I clicked to continue, however, it restarted at the beginning.

If you fly with the simulator (available in the sidebar) do you still have the same issue of continuing a mission? This will help us determine where the issue is.
