Show/Hide fields not working for Condition Fields on node display
This is a quirk of the module, per the documentation on the view context:


  The "Value", "Filled" and "Empty" conditions are special: they are the
  only conditions that have ANY effect on form validation and content
  view.


If you want to show/hide fields with the module during content display, you'll need to set the Condition to Value and the according value for your checkbox.
