Help with an Inventory Tutorial Please

Hello,
I am trying to follow this tutorial Inventory System | Community tutorial
The tutorial was created in 5.4.4, but I am using 5.7.

I am on step 3. Inventory UI. Trying to create the blueprints shown for the Inventory UI.

This is the Blueprint I am trying to follow:

However, I cannot seem to get the Set node that has both the inventory and the target. And if I copy the code, the Slots grid UI does not match the Target object reference so I cannot plug them in.
Here is what I am getting if I try to just set the Inventory I cannot connect the Slots Grid because there is no pin for it

If I try to copy the set node from the tutorial, I get this

I now have a set node with the two pins on the left, but I cannot connect my slots grid.

If anyone could help me figure this out I would greatly appreciate it!
