"professional 5 to 9" is the difficulty level, not a skill.
And it should be saved when you change it. Do you have an old version ? If yes, update to the v1.0f , maybe it'll help.
If you use the function "watch all matches", you have to change the difficulty of the viewed matches in "World Tour -> Misc Options -> Watch All Matches -> Difficulty".
