I replaced mine that came with car (non-oem style, same lengths on left and right side, right side didn't quite fit right) with the the Bosch OE style matched set. I honestly can't remember if I had the problem you're mentioning, but I'm sure if I did I figured something out. Weren't there several adapters that came with the box - and one of them worked?
But anyway, I like the OE style wipers because not only is the right side shorter, it's curved (which is kind of a fun, unique Porsche thing IMO.). Also the curved blade seems to tuck down a bit more nicely out of the way when not being used / "parked".
