Behavior Tree Services Wont Work

Hi everyone! I am using Services to test when a AI is close to the player. If the distance of the AI is <= 500 then the AI will chase the player. But whenever I am far from the AI the AI will not stop following for some reason.

Alright instead of using services I decided to use timers in the actual AI blueprint and now everything works. It turns out that the distance in timers and services are way off from each other! I think it might be a bug but whatever… Everything works now.
