I think the honor points counter is sometimes bugged (only clientside).
If you complete another kata (any level) , your counter will probably be updated with current kata points and your last kata points (kyu5 here)

For instance
// I got 600 points . I complete a kyu5 (8pts) . My counter goes to 602 ( :'( )
// I complete a kyu7 (2pts). My counter goes to 610 (602+8)

Awesome ;)
