Miles & More (Lufthansa, Austrian, Swiss, and other partners) - Strange Seatmap

I just checked the seatmap for one of my bookings (LH438 on Oct 17). It is an A340, but the biz class starts with row 4 (and not row 3 as norma) and C has 42 seats. Anybody knows if that is old or new biz and why it suddenly starts with 4? It is hard to believe that they have squeezed an extra row in F.....

Thanks Stefan

Probably one of the ex-Sabena (34Z). See

My recollection from flying Sabena longhaul is that they did not have F class. The flight I am booked on has a F cabin..... Anybody else an idea what that could be?

Thanks Stefan

LH 438 on Oct 17 does not seem to have F (at least as of today, checked on amadeus.net).
