Purchased DUNE 2.6...seeing 2.5 in Logic

[orema30]

I am running OSX 10.10.5 and I use Logic Pro. Upon pulling up DUNE 2 in the AU Instruments folder, it says DUNE2.5. Is there something that is wrong with my set-up, or is it just nominally showing up as 2.5 and runs similar to 2.6?

Thanks in advance
