In my opinion, the style discussion is a wild goose chase. The problem sounds like it is to do with the options set for that section.
Every section can have up to 3 different headers and footers. When you are editing the footer on the first page of the footer, pay close attention to the popup info box on the dotted edge of that footer. If it says "First Page Footer" then that footer would only appear on the first page of that section. You can turn this off by unchecking the "Different First Page" checkbox in the ribbons Header & Footer Tools>Design tab. If you also ensure the "Different Odd & Even Pages" is turned off too then your section will only have one footer displayed and any change you make will be reflected in every page of that section.
