You have to check whether the shows actually have guide data. E.g. go into the To Do list for one of the shows that you think is a rerun that is being listed.. and hit the Info button. Does that page now tell you an Original Air Date that is within the last 28 days?
If NOT, check your Season Pass to absolutely confirm that it is set to First Run Only.
The show might have 'generic' guide data, and the Tivo is recording it anyway, since the only reasonable assumption it can make is that it might be a new episode. (Yes, we logically know that network shows for example don't show new shows in the summer.. but e.g. there are burnoffs, or some other miracle might happen, so the only logical choice is to record it by default.)
