Gallery categories showing wrong in WYSIWYG

Hello there,

I encountered a problem when using your plugin. When using the gallery shortcode in a post [gallery category="52"], the code makes the correct images render on the frontend page, but loads ALL (yes, ALL of them) images from WP media library in WYSIWYG editor when editing the post.

Any idea what is wrong?
