Race/Path Editor's difficulty selection is bugged

Editing and re-saving a time trial changes the selected difficulty one step harder.
Selecting Easy (24) in editor turns to Medium (37) in game.
Medium turns to Hard (62)
Hard to Very Hard (87)
Very Hard to Unknown (112)

The race.json must be edited to change it back.
Other than that the race/path tool feels convenient and easy to use.

 

Oh, is that why my difficulty is always out? Makes sense now. I did always wonder.
