Behavior Tree Quick Start Guide not working

Step 11.5 copying code into service editor produces errors, a pile of nodes, no variables etc.
Also, msg below jpg of graph says: Click the image to expand it, or click here to open it in the window. BUT window not found (same for the function diagram below this)

Thanks for reporting this issue! I will pass this along to the appropriate contact here at Epic Games.
