Only some TV shows are showing up

I have downloaded all 4 seasons of News radio and have them on my hard drive. Sapphire only shows Season 4 Show 20. None of the others show up in Sapphire. they show up in NitoTV, but not Sapphire. All of the shows are named the same way.
I have deleted the metadata for the drive a few times but it still refuses to show them.
Any idea what I can do to fix it?
