Clicking on a language tag doesn't work as expected

For example, if I click on « Norwegian » in Gonzojournalisten Vinje del 1 - Glan, the result is two channels, two videos where the language is set to something else than Norwegian, and after that, videos with the language set to Norwegian. What I really expect, is only videos in Norwegian.

It’s the same for other languages. Clicking on the category, however, works as expected.

My server is set up to use Sepia Search by default. However, filtering by language works perfectly fine when using Sepia Search
