Blueprint Graph Variable not showing

I was doing this tutorial: https://docs.unrealengine.com/latest/INT/Engine/UMG/QuickStart/4/index.html

And on the step 5 and 6 I’m not showing the “MainMenu” and “OptionsMenu” variables in the graph.

In the Designer all seems correct. I have my hierarchy exactly like the one in the tutorial

But the Vertical boxes are not showing as variables in the Graph.

Can anyone help and tell why and how to fix?
Thanks in advance
