Trouble with Tokens and deleting pages

Hello,

I was reading the thread on how to delete unwanted pages at the end of scores. See attached.


The problem was, when I went to Page 15 and selected to delete the overrides, my first two pages were also deleted in the process. (MY title page and instrumental layout pages were deleted and a valuable part of my project naturally)

Can someone walk me through this process so not to delete anything of value, except for the empty pages at the end?

Thank you so much,

Amanda
