version 5 Odd behavior with grid and child

Hey guys,

I’m starting with UE, I’m trying to create an inventory with uniform grid and slots. My slot, it’s just a HUD with a button and a text.

I wanted to make disabled by default empty slots and when I pickup an object, make the used slot enabled.

When I’m playing with enable button feature, and pickup more than one item, my used slots become more and more lighter.

If I just change the color for used and empty slots, it’s working well.

Any idea ?
