Why four different Catalyst Control Centers in Software Center?

[Feanor's Curse]

Hi. I recently upgraded to 12.10 and there seems to be no option for the restricted drivers. So I went into the software store. But there's four different versions of the center, all with the same name even! I'll try to find the correct version myself, just want to point out that having four times the same name and description isn't exactly what I'd call userfriendly.

Cheers
