Setting a cruise altitude close to the max cruise altitude sets the cruise speed way below minimum

Which aircraft are you experiencing this issue in?


Are you using Developer Mode or made changes in it?


Have you disabled/removed all your mods and addons?


Brief description of the issue:

When flying today, I wanted to set a higher cruising altitude than I was supposed to be at at that point in the flight so that I could go to sleep with the plane at a higher altitude and not miss a step climb. The max indicated was around FL367 and my initial cruise was at FL340. After setting FL360 I noticed my econ speed had gone down to M .494 which is totally wrong.
