Collection not working for single set

Hi

I am new to XBMC so I am sorry if my question has already been answered. I made some searches but could not find the answer. Basically my question is why my Jack Ryan movies are not in the Jack Ryan collection? I checked the web site for the MovieDB and they have a colleciton for these. I don't believe it is a scrapping issue as the movies are detected fine, they simply are not part of the collection. All the other collections I have are working fine. I completely removed all my sources to clean up the library and start over but I have the same problem.
