Miranda Cosgrove tweeted here that it was Season 6: https://twitter.com/#!/MirandaCosgrove/status/162294729671847936. But it makes sense why Nick would call it Season 5 because of the number coding. But it's clear the Season 4 and 5 are not one airing season as I explained above.

CheckerFred, I emailed those Nick people about the same thing, but never got anything back for more than a month now.
