UMG Inventory in UE4 tutorial: Animation not working

There is an array of issues with the UMG tutorial series on Youtube and would greatly appreciate some help on how to fix it, the problems are as follows:

The inventory animation isn’t working

‘Action menu’ text is visible but ‘inventory’ isn’t

Inventory slots are also invisible

Item pickup isn’t working

The health, Energy and Mood is missing on purpose as I only wanted the inventory.

Can post up screenshots of the blueprints if it helps
