PawnSensing bug that I have no idea how to fix

Basically, I am creating a horror game and my enemy has a chase ai with pawn sensing and pawn perception. I have been following tutorials and don’t know why this bug is occurring. When my character is in the sight radius of the enemy’s pawn sensing it will not react and start to chase him and then sometimes it will. I have been trying to figure the issue out for around 4 hours and cannot find a solution to the problem.
