Why is Literature a gray link for every title in the database, even if it has literature?

For every title in the database, Literature appears as a gray (supposedly inactive) link -- even if the film does have Literature to list. Below, you can see an example, where Bonnie and Clyde (1967) has Literature as a gray link. But, in fact, http://www.imdb.com/title/tt0061418/literature shows that the film has eight different items listed under Literature.



This is the opposite problem from the one I described in the thread at https://getsatisfaction.com/imdb/topics/why_are_publicity_listings_a_blue_link_for_everyone_in_the_d.... Every individual in the database has a blue (supposedly active) link for Publicity Listings, even if the person has nothing to list there.

Can you please turn Literature into a blue link for films that actually do have Literature to be listed? Otherwise, some users may miss literature information that they would have wanted to see, assuming that the film doesn't have any literature listed due to the gray link.
