I'm having some problems with an RSS feed for a custom post type. If you view this URL http://intentional.wpengine.com/feed/?post_type=30daychallenge you'll see a raw feed. Everything looks to be fine there. The problem is when I burn the feed or try to use it in an RSS feed to post plugin (like wpematico or similar) the post type query disappears or something as all of the posts from the site show up in the burnt feed and the plugin data.
Any idea what could be the problem?
