Mob using skills when it shouldn't

I've been messing around with this plugin, and I'm trying to give a a mob a leap smash attack to use when a player or villager is within range. However, the mob attempts to use the skill even when nothing is in range. How do I make it so that it only uses the attack when a player or villager is within an 8 block range?

Also, the explosion effect thats supposed to happen at the end of the leap seems to happen before the leap for some reason

here's the mob file
