The order can't be fulfilled, the navigation will take me there, but there is no red flag and no green box to respond to the order. Normally I would have let it go, but it was quite a long route, from St Petersburg to Lisbon, and it took quite a lot of irl time, and not being able to finish it is quite frustrating. There should be a point near the gate (see the images).
Thank you in advance for all the help.
