Bug when using only one language?

[roboy]

Hi everybody,

I have been playing around with my first installation of Prestashop and must say that I'm pretty impressed. Open source is power!

Now to my issue: I want to make a shop with only one language - Swedish. So I installed the Swedish language pack and then deleted English and French. Everything seemed fine until I wanted to add new products or a new category. As you can see in the attached screenshot the form fields have been replaced by flags. When I click the flag a white rectangle appears where it says "Choose language:", but nothing can be chosen.

Did I actually discover a bug in the code here or is there perhaps something that I have neglected in the configuration? I'm looking forward hearing what you have to say about this.
