conflict with custom post types and marketpress

We have several custom post types on our site (not thru custom press) we are running into a strange issue where if we have marketpress activated, one of the cpts dissappears from the left nav admin menu (but still appears in the upper new+ menu). When we deactivate mp the 3rd post type reappears.

The post type slugs are: trails, recipes, and reviews.

Oddly enough if I move the code for recipes above the code for reviews(in the post-types.php), then recipes appears, it I move it back down below then reviews appears. It's as if it is only allowing a certain # of cpts outside of marketpress.

Is there some sort of cpt conflict or limitation to the # of menu items within the marketpress plugin code?

I've attached a screen shot.
