Ubuntu - Searching for season fails

Hi,
I’m trying to fetch a backlog from a certain season. I’ve set some of the files to monitored and then clicked on the search for all episodes in season button. The popup message shows that the search is starting, followed by an immediate fail. In the logs, I see the following:

Automatic and manual search works for a single item, so it just looks like there is some issue with the lists.

I just updated to 512 and ran the search again and it works fine. Whatever has changed has sorted this issue for me. Thanks!
