AI Random patrolling

Hi, I have a problem with creating a task (for behaviour tree) for my bot. I created a blueprint, but it doesn’t work properly.

My bot never goes to the point where it’s the end of the line trace. In the picture it’s the situation where bot should go to the south-west box. Why does he go to the other place? I want to expand this scirpt in the future, so my bot should always go to the right place.
