How do I de i make each enemy have a different LOS?

So when the player gets in the LOS of the enemy, it starts shooting at the player. But it seems that all the enemies have the same LOS, so when one enemy detects the player, instead of that enemy shoot, all the enemies shoot.

I have no idea how to fix this

You might not be picking the specific enemies that have LOS. You can use "for each enemy" and "enemy has LOS" conditions before your shooting actions to make sure only those ones fire.
