Whenever I choose "Set Board Outline" and change the X, Y, width or length, it enter a different value and changes the other ones. Example:

I now change Height to 22 mm:

I Click "Apply" and enter the same dialog again:

Now, it has set the Height, not to the 22 mm I entered, but to 23.016 mm, and Y has changed from 121.476 to 120.968 mm even though I didn't even touch that field!
Is it not possible to enter the exact values I want?
Best regards,
