Any option that was set to be Default or Customize Off means that it will use the value of equivalence option you have set in Preset (if this page apply any Preset) or Theme Options. Insert a different value to override the Preset/ Theme Option value.
Preset and Page Options will use the Theme Options value if left empty or if the value is default. They will override Theme Options if any other value is entered. This setup gives users maximum flexibility for setting a global theme option, then being able to override it on a page/post/shortcode basis
