Why can I only watch the first season of Spongebob Schwammkopf at netflix?

Then only one season will be available. And something like premium membership does not exist, there are 3 prices - and the only difference is that the image quality is different and different number of users can use the account.

1. There's no premium
2. Only the first season

With my Netflix there's no Spongebob at all except the movie
