Mouse down does not trigger if widget starts as hidden

Development Programming & Scripting Blueprint

I built a drag and drop inventory system based on the inventory training. The HUD contains the inventory panel however I’m not sure how to start with the inventory being hidden.

If the HUD has the inventory panel set to visible one can drag it (although it leaves a strange first child upon dragging). If panel is set to hidden either in the HUD or programmatically on beginPlay, the panel can be seen with the corresponding inventory button (I) but no longer triggers mouse down on the widget.

What is the proper way to handle hiding and showing inventory so it can start as hidden?

After creating a new testing level I was able to bring up the inventory with it’s corresponding I key and drag and drop as expected with no issues. Really strange as the previous testing landscape had only my character and a few dragged-in items for testing. Nothing else changed literally created a new level and was able to recognize the mouse down event and drag widgets and items around where in the previous empty level it still doesn’t work.
