The amount of contamination you found doesn't surprise me.  It's amazing how many ways nursery stock can become mislabeled.  Primocane berries being allowed to fruit  and drop seeds in the nursery, canes layering themselves across rows, workers that can't read, sloppy planting/harvesting, deliberate mislabeling to fill orders, etc.

As an example, I've recently been working on developing genetic fingerprints of black raspberry cultivars as part of my PhD work.  >From just two different sources, I have found at least 5 different clones being sold and distributed as the variety 'Munger'.  Four of these came from the same nursery!  Both of these sources are highly visible and reputable, and the differences are much larger than can be explained by sports or somatic mutation, and there are probably many more out there that I haven't uncovered yet.  This isn't an isolated case either, there are problems with many of the other cultivars as well.  Unfortunately I've seen this over and over again with all kinds of things, pear, plum, cranberry, red raspberry.
