With your movie selected in the menu, choose the IMDB button. This will take you to the movies IMDB page. Check to see if the information you are after is displayed. This page is where MC gets the information from. If its not populated then MC can't retrieve it.
If it is & recraping the movie doesn't fix it let us know the movie & we can have a look. IMDB sometimes change things around & we have to modify MC.
