How/where to begin an ebook

I’m having an issue with Scrivener. After I upload my ebook to Amazon and preview, It gives me: TOC page and cover, both which work. But when I click Beginning, it goes to the latter half of the TOC page. I heard someone mention Front Matter, but I can’t find that file anywhere. Please help.

There’s not a way yet in Scrivener to set a specific start page for ebooks, although that is something on the list for the future. You can however do this yourself by compiling to .epub rather than .mobi and editing the file in a tool like Sigil, which will let you easily alter the OPF file to add a start tag, as written here.
