The program crashes if there are any entries listed whose season isn't known yet and I try to sort by season.
I discovered this because I wanted to sort my "Plan to watch" list by season in order to get the ones that already aired.
It would probably be best to just treat these entries as if they were in a season that's newer then any other season. That's also how they do it on the MAL website
