[Plugin: Posts 2 Posts] adding more than one connection issues

I tried the following code:

function my_connection_types() {
    p2p_register_connection_type('movies', 'actors');
    p2p_register_connection_type('movies', 'directors');
    p2p_register_connection_type('movies', 'genres');
}
add_action('init', 'my_connection_types', 100);

This does indeed add all 3 fields to the connections box on the movies admin edit page as expected. However there is one issue with it in that when I assign an actor, director, and genre to a movie, and click publish, only one of the fields is saved.

Well the fields are actually saved, but only the first one is shown as saved when I click publish, the other fields return to their blank state.

I can provide a link if necessary for troubleshooting.

also:
It would be nice if instead of placing all 3 fields into a single box called connections if I could separate the 3 boxes out so it makes more sense to the user inputting the article.
