Help: Different piezo saddle in JP6

Today arrived my JP6 and what concerns me is that one of piezo saddles (E6) looks a little different (I mean just this small pin). Piezo works perfectly, it’s just visual thing and it bothers me a little 😀
SO main question is – where can I buy new saddle(s)? I’m located in UE.

Edit: sorry for the dust, i’ll clean it later 😀

Cheers,
Peter
