This happens on my TiVo as well, so I suggest that this is probably a normal operation of the way things work. What I find that I can do is either wait until the next time TiVo updates closer to the day and set a Season Pass, or add it to the Wishlist.

I know it's not extremly helpful at all, but it's one step towards what you want to do.
