Use of pages on my ipad

For years I have used "pages" to store my info and recipes. Lately when I go to a blank page and begin typing or try to paste something it jumps off the page and goes to the original "pages" with all the previous things listed.

Also when I begin to type I get a blue outlined rectangle at the top enclosing the title.

What am I doing wrong? Is there a setting that was changed? Thanks to anyone who can answer this.

As of today I am unable to type a page without it jumping off and going back to the original.

This keeps giving me the option of pages for a mac. I am not using a mac but an ipad.
