Netflix question? How to add different seasons of shows onto the instant quieu?

I have Netflix on my bluray player. I have to go online to add movies
or shows to my instant quieu before watching on my tv. So I added the
first season of a show onto my instant quieu. It has all the seasons
of this show, but I have no idea how to add the other ones. I clicked
on season 2 but when I went back up to where you add it to the instant
quieu, it still said add season one to your instant quieu. This is
annoying me, I need help
