Strange behaviour route after data exchange

Hello, I used the new data exchanger to transfer a route, gribfile and polar from a Windows 11 desktop to an Intel Macbook. The transfer worked flawlessly but the route on the Macbook behaves rather strange.
When time stepping through the transferred route, the boat leaves at the original time but not from the starting point but from the destination. It than follows the route in the opposite direction back to the starting point. Not back in time but progressing from the original arrival date. While doing that the line of the route is erased in the wake of the boat.
Regards, Ruud
