Modal wrapper for newsletter unable to convert in Symbol or it loses its close interaction. WHY?

I created a modal wrapper for a Newsletter action and when I tried to convert the modal wrapper into a Symbol (it’a going to appear in every single page), then the close interaction doesn’t work. It’s happeing always I try to do an interaction between a block out of the Symbol and an element inside the symbol.

Trigger: Newsletter down (footer)

Can someone help me?
