I'm trying to create a filter for a show. The season that just concluded is S07, but now I'm getting season 7 episodes again and I realize I have to set up Smart Episode Filter. So I figured that, just for good measure, I'd set up the filter so it doesn't download anything before season 8. So I put "8x1-" in the filter but it's red, indicating that the filter is invalid. I have a similar filter for another show that is white. Why is this one red?
(BTW, even though it's red, it still apparently works, as the shows that match when it's not filled in disappear when it is.)
