Enemy character doesn't reach player despite, it is faster

As you can see from the video

the enemy is faster than me (otherwise, it would not come close), but it can’t reach the player for some reason when beeing close to it. This just happens, when I set the max movement speed of the enemy to something like 800 or higher. Under that, I at least can’t see the effect appearing. The enemy is just a normal character with a normal character movement and I move this character with the “Add Movement Input”-Node from the Graph. Any Ideas? Thanks for answers!

Ok, I still don’t know what the mistake is, I just remade the whole Blueprint and now it works fine.
