AI roaming when possessed and unpossessed does not roam again

Hi, I am a beginner in using Unreal. I have a AI that is roaming at the start and when the third person character possesses the AI. I can control the AI but when I unpossess the AI character and go back to the third person character the AI does not roam and just stands there.

These are the blueprints to possess the third person and the AI.

  1. Blueprint show Third person character sphere collision hit the AI character, player controls the AI character.
    In the Third person character added a sphere collision on the Third person character. In the event graph created this blueprint showing when Third person character’s sphere collision touches the AI character shows a widget blueprint, when moving away from the sphere collision the text disappears. Click “E” on the keyboard possess to the AI character.

  2. Blueprint show AI character sphere collision hit the Third person character, player controls the Third Person character
    In the AI character, added a sphere collision on the AI character. In the event graph created this blueprint showing when AI character’s sphere collision touches the Third person character shows a widget blueprint, when moving away from the sphere collision the text disappears. Click “E” on the keyboard possess to the Third person character.

  3. Blueprint shows AI roams around.

Can anyone please help me to add to these blueprints to have the AI to roam around after possessing the AI back to the third person character. Thanks
