Sonarr not finding episode

Normally I can figure out what’s wrong with a specific indexer or serie why certain episodes are not found. But with this specific serie I cannot figure it out. Sonarr only finds 2 episodes but while browsing kickass.to there are a lot of episodes.
I have " only verified" on disabled on the indexer, and running latest master 3004, also there are no filters active.

Serie: The last Man on Earth
Episode s01e04

KAT seems to have broken their API (when cateory:tv is used), not sure if thats intentional or whats going on, but they should fix it.

Ah, that’s why I couldn’t find it what’s the issue is. After editting the url, and removing the tv category it indeed shows all the episodes.

*edit: i’ve submitted the error to KAT: https://kickass.to/community/show/api-tv-episodes-search-bug/

KAT seems to be have fixed the issue, so this can be closed.
