I have a widget I can't find to delete it

Hello again! I put a placeholder on a page and embedded a youtube video in it and it worked as expected. I have deleted it and replaced it with a smaller size. Now the large size thumbnail is stuck at the bottom of the page when I preview it. I moved the second one to a different page but still have the large thumbnail at the bottom. How do I find the missing widget? I attached the xar file. The page is "technical".

Thanks in advance!

Found it! Somehow in my cut and paste session the code ended up in the page body which is why I could not find the non-existent widget.

Whew!
