If you go to the header in the second section, presuming it's blank or different, look on the Header and Footer ribbon close to the center, under the Navigation section, and click on "Link to Previous." That should pull the characteristics of the previous section's header through. I believe you will have to do the same in the Footer space.

I think the default is that if you put in the header and footer in the first section when creating from scratch, it will default to Link to Previous as subsequent sections are added. But I just made a dummy file to test it and "different odd and even pages" came up by default on the second section, I'm not sure why.

If you need to start a different page number sequence (for example, some of our reports have an executive summary which gets a i-ii-iii type lower case Roman numeral along with the table of contents, then the main report starts with 1-2-3), you'll use the Page Number settings on the ribbon of Header and Footer to tell it to start over.
