Page builders will not open the page I made

I can make a page, put stuff in it and set it up in the navigation bar. I can hit on the tab for that page it shows and everything, but once I try to go back to that page in page builders it won't show, open or anything. What happen? What can i do to fix this? and how can I delete that page from the list  since I can't open it.

This drives me nutts because I plan on going back to these pages daily for updates

Because your new Page URI are more than one  word, add pages like this and it will work

Page URI: test_page

Page title: Test Page

You can edit your page on table sys_page_compose_pages

look after the last inserted row and edit Name on your  page to one word.
