Motion Matching Jumping over Objects does not work in my project.

I migrated the motion matching from the game animation sample. The motion matching itself works, but then I added a levelblock traversable in my map and the jump over it does not work right. It looks like the Character is always going over it with a height of 2 times of the levelblock itself. I have no idea why it is like that. The animation for going over it are also working, the character just does the animation in the air over the levelblock…
