How on earth did they mislabel three rose bushes???? Where did you buy it?
It looks to me like Carefree Beauty. Here's a photo that I think looks a lot like yours.

I suppose it could also be one of the earlier Austins without so many petals, but I don't have very many of those and I don't remember any in that color. It really looks like a Buck rose to me, especially in view of the lack of clustering. Here's the main listing for Carefree Beauty. See if the details match. There are several pages of photos if you click on the photos tab.
