Theme purchase issue (breakpoint and pages)

Two questions:

  • I bought a theme and can’t seem to duplicate a page per the theme instructions (it says ‘Maximum Number of Pages Reached’ when there are less than 25 pages in the theme by default)
  • The theme has breakpoints by default for different screen size, I don’t want those and need to remove them, how do it? Alternatively, how do I apply a change I make to all screen sizes?
