3D inventory won't update to item pickup

I’ve created an inventory system based on the inventory UI with UMG provided by epic. whenever I pickup an item the inventory doesn’t update to show the item. Right now the widget is attached to the character as a 3d object to follow the player around. I have to keep the inventory set to visible as well because it also won’t appear when i set it up to open with a button press. I have the image of the item set up so it should at least display it, but it doesn’t even show my hover event. I’m not sure if it not working because I made it a 3D object or what, but it’s been driving me crazy for days and I can’t move on until it’s finished. Any help would be greatly appreciated.

For an easier way to explain this, even when I use the Inventory UI with UMG provided by epic, if i turn the inventory into a 3d object it no longer updates to add items. The health bar still updated to eating food in a 3d object, but the inventory doesn’t do anything
