Mission Failure - At Parking Spot, Can't End Mission

Do you have the same issue if you follow the OP’s steps to reproduce it?

Provide extra information to complete the original description of the issue:
• I just did an hour long flight in a Robinson R66. After taxiing to the parking spot, it prompted to set the parking brake. I was not able to do this because it was a helicopter and even a shutdown and application of the rotor brake would not complete the mission.

If relevant, provide additional screenshots/video:
