UMG conflict

Hi. I’m having this problem with UMG:

I have an in game GUI made with UMG which display life, money, pause button and stuff, then, i have random spawnable blocks that create other little UMG (see video). These blocks are dinamically generated and always different so i cannot put all the stuff into one UMG.
The problem is that UGM doesn’t overlap correctly, and I can’t find a way to make them to communicate.
In particular, I want that if pause button is pressed, the menù interface cover all other stuff and disallow player to use buttons from other UMGs

As you can see, text from “Bartender’s UMG” overlap “pause menù UMG”

up, heeeeeelp pls
