Hey Romanek,
Based on your post history the issue you’re having is similar but unrelated to the widespread issue with commander levels resetting to level 5.
In your case, I would recommend to try deleting the Blizzard cache folder then launch Starcraft II again so it will be rebuilt.
If you’re still experiencing the issue please submit a ticket using this link and attach screenshots of what you’re seeing in-game.
As the original issue discussed in this thread is resolved we will be closing it. Thanks.
