Check out this thread regarding certain labels issuing titles on CDRs:

If you've gotten CDRs from Caiman, that's probably the way they came from the manufacturer. I've purchased probably hundreds of CDs from Caiman over the years, and never received anything other than actual genuine label issues. The only complaint I've ever seen about Caiman--and I've had this problem, myself--is that they often list titles for sale when they or their suppliers don't actually have them in stock. I've NEVER seen a complaint about the quality or genuineness of the actual product once it's received. Caiman's pretty good about returns, however, if you don't want to keep the CDs (or CDRs, or whatever they are).
Also, it's not uncommon for European CDs, although brand-new, to not be wrapped or sealed--that's the way they come from the manufacturer. For example, I've purchased several brand-new European Blue Note CDs from various on line retailers that were not wrapped or sealed.
