Why I can't buy a bundle?

You need one stuff pack, one gamepack and one expansion pack for a bundle right?
I still don't own two stuff, realms of magic and university, and when I go ingame and click on get a bundle on main menu after it loads to another page and tell me I'm a collector and own too many sims 4 content!

Is there something wrong? Should I delete origin cache? It doesn't make sense..
