Little problem with armor slots.

Hi.

I think I discovered a problem with the armor slots. Here's the thing:

-I made a chestplate that gives you Health Boost when you wear it. 
-I want this effect to be removed when the player is no longer wearing the chestplate.

I tried many ways to do that, but with no success. I think MCreator has a problem with detecting items within the armor slots. 

Here's a procedure that I created in attempting to do that:

I created a very short and simple procedure to test what would happen if I was wearing a diamond chestplate to remove all potion effects. It doesn't work. The health boost effect stays in place even if I wear the diamond chestplate. What should I do? I use 2025.1.
