Switch BTree while active stuck on 2nd BTree


I have a question. I want to use a boolean to go back and forward with controlled or not controlled. I have it set up to when the beam BP overlaps the friendly AI they become controlled and start to attack the player character. The problem is its stuck on controlled and keep attack the player. How do I have it change back to Friendly AI Uncontrolled? Like a timer. Only for a few seconds. At the end I set isYitilba? to off but it dosent even fire nor does the print string at the end that say “Yitilba Over”. The Friendly follows the player character and when the player capsule collides with the beam The friendly attacks the player character. Now how do I simply go back to Friendly AI following the player and stop the attacking witch is Controlled? I got it to go from uncontrolled BT to controlled BT. How do I simply make it go back? IsYitilba boolean must be on for the AI to be controlled. Thank you.
