I would probably need to see the scripts you are using to help you solve this. However, I have a feeling it's because you're not using the right block, so try the following:

Whenever you check the enemy's health to make it hide, instead of using

<(health) = [0]>

try using

<(health) < [0]>

(note the different sign in the middle). This will make it hide even if the sprite's health went below zero!

Sometimes a problem occurs if you have duplicated a sprite and used the same 'personal' variables for them both. Try changing the current

 (enemy health) 

for variables from the palette for each of the enemy sprites.
     Basically, try getting rid of the current variable blocks and adding new ones in, for each of the enemy sprites. I hope this makes sense and I hope it works too!

(also you may want to change your current if < (enemy health) < [0] > to if < (enemy health) < [1] > as that way the zombie will not be alive even if it has health = 0    )
