Page Numbers - Kindle

When I create and open the Sigil ebook in Kindle Fire Previewer, It automatically starts on the third page, which is actually showing as page 17. How do I get it to start on the cover page?

For some reason it skips pages ...
-page 3 is shown as 17,
-page 4 is shown as 32

and so on.

I'm hoping it's a simple fix with my format or html???

I'm not looking to chit chat, just a solution please .
