With Genesis 2.01 and WP 3.71 this adds extra <p></p> tags between image and image captions.
I deactivated the plugin and the extra <p></p> tags are removed and normal caption spacing returns.
This occurs using both the WYSIWYG or text editor. Please let me know when this issue is fixed because this is a very helpful plugin - I prefer to using the snippets in text expander. Easier for clients, too.
