Having difficulty starting page numbering on 9th page

I am having difficulty starting page 1 of my manuscript on the 9th page of my book

I’m clicking on page eight inserting a manual break
choosing default page style and changing the page number before the desired next page but it is not working.

Can someone help me as to what I am doing wrong. Thanks for your help!

Please give more details about your document. Basic information: OS name, exact LO version (as reported by Tools>About LO) and save format.

What are your first 8 pages? Are they also numbered, kind of first chapter?

Are pages 9+ a “continuation” (layout-wise) of the preceding pages or something completely different?

Basically, Insert>More Breaks>Manual Break is the way to go.

If you still can’t fix it, attach a sample file.
