When going in to the Load Template interface, there are a couple issues.
One, is that the dropdown is mis-aligned off to the left. And the button and dropdown are different heights.
Also, it displays that uh-oh message below the template selector, and there’s no way to select where to insert the template like the previous version (below):
Lastly, inserting templates doesn’t appear to actually work. It shows the success message 
but the template doesn’t get inserted on the page anywhere I can see.
