All issues except #3337 are a result of either a Joomla bug or Joomla misconfiguration. MyCommunity and Coolness don't have Content template overrides so it is literally impossible for them to cause #3340, #3339, or #3336. Funlite does have a Content template override, but it is not causing any such issues (confirmed). Please note we confirmed all issues are also present in Joomla default templates so the chances are high this is a bug in Joomla it self.
