I installed ITPSocialButtons-Plugin in my joomla site.when I activate this plugin and media section is enable in k2 item view parameters, the media section of k2 appear however the media its exist or not.
and also share buttons appear twice in k2 items, one in content of k2 items and the second one under the media section when media section is enable in k2 parameters.

Hello,

If this is not an issue with the plugin itself, use the default template in order to see if the plugin is behaving correctly.
If that is the case, then it is a template error (the plugin event is present twice instead of once).
