I followed UMG UI inventory tutorial from official site, everything works fine except whenever I open inventory after picking up an item, the item does not show up in inventory and the inventory shows the item that I pickup empty.
Here the tutorial : https://docs.unrealengine.com/latest/INT/Videos/PLZlv_N0_O1gZalvQWYs8sc7RP_-8eSr3i/GFBv_69VLzs/index.html

Have you checked to see if the item is being added to the array?
