Selecting TV Shows in iTunes

Something odd is happening in my iTunes!

I took advantage of the 12 Days of Christmas offer and downloaded Season 1 The Rock and House. I also downloaded Top Gear Special and The Trip.

Now, all I want to do is have The Trip on my iPhone 4.

So, I clicked on All Unwatched/Selected Shows/The Trip.

Now all I have it The Trip with a tick in the box. Nothing else is ticked.

But when I sync 30 Rock still appears on my iPhone.

Am I doing something wrong? Or is this another glitch on recent Mac OS?
