Did they redesigned the Accu Tac PC4?

I just received my Accu Tac PC4. From the website I ordered from and many of the photos I've seen, the lever for the panning lock is at the bottom of the housing. The one I received has the lever on the front, opposite of the lever for the cant lock. What gives? I was thinking I preferred it to be at the bottom but if they redesigned it to be at the front, it will be more difficult to get the bottom lock new now. One positive for the lever on the side is if I have to rest the bipod onto something while it is in the stowed position, the lever won't be sticking down to prop and make it unbalanced.
