Purchase of Fortnite only shows free version with re-purchase of founders needed?

I'm aware you can't play until 10 ET, but after purchasing it the only option I have is to actually purchase it a second time, with the free version being the only one able to download / rate etc. I know the servers aren't live, but this has never made any difference with pre-order games.

In other words, I buy the £32.99 version, it gives me the free version (which I could have downloaded anyway) and won't show the 32.99 version as purchased.
