Looked into it today, it seems it is not even register anything, I looked at the AI and found out there was no Sight or Damage Sense, so I added them. Will be seeing if I can use Damage to a Unit as a prompt to Attack the Attacker, or see if I can set it up to if the Attacking unit enters a radius that the Defender can Attack. I will keep updating this thread, if anyone knows how to set this up please let me know. The pic is the part that was not added on the AI:
