I encountered a bug when manually searching for episodes within a season.
When searching for one episode, the result comes back with the right hit (example s01e01)
But when searching for another episode, the results are that of the previous search (example s01e01 from before)
And so it goes on, returning only the result from the first search, no matter how many times or what episode I search for.
I have to leave the season page and enter it again, for being able to search correctly again. And then it starts over.
The bug does not occur in the Sonarr GUI.
