"Only Show Distinct Shows" no longer works

[skd5aner@…]

In the search page, the checkbox for "Only Show Distinct Shows" no longer work after upgrade to 0.28 from 0.27. Only show distinct shows should only show a single result per show title.

One way I test this is to search for movies from 2015 to 2016. I will see the same show displayed several times in the results, instead of only once. This makes looking at a unique list of shows very difficult, as there are repeated entries for every showing of that show now that it's broken.
