How to delete a blank page

While I was messing up moving blocks of items (see previous post), I accidentally created new blank pages above the pages I was working on. “My” total Scapple is 6 pages high and 4 pages wide including the 4 blank pages above my items.

So, when I print, I get 4 blank pages in addition to my Scapple. Yes, I can select the pages I want to print individually and print my Scapple. But, what I want to do is delete the 4 pages above my items that I accidentally created. (still don’t know how I did it) and then print as I would normally.

I can’t figure out how to delete the blank pages. How do I delete a blank page?
