From the description and picture on the Bitzenberger website, it has a different indexer and clamp from the regular Bitz. The base looks the same, but I'm not sure. If possible, you should exchange it. The price is a few bucks higher than the regular fletcher, so you should either get a few bucks back or break even on the deal, other than shipping.
Before you exchange it, you need to decide if you want a right or left wing clamp. I would probably stay away from the straight clamp.
