Supermicro 6029P-E1CR12T. M.2 Design Flaw?

Hi,
We recently bought a Supermicro 6029P Barebone and i dont know if it is just me but it seems to have a major design flaw on the way how the M.2 drives are fasten.

The diagram (Page 47 of the manual) says for M.2/80 Cards to put the lock in the first hole of the "plate" but there is no hole on the board there for it to sink into or fasten for that matter. so the lock bit is too high, then it says that the card fasten bit needs to go in C (taking up the lock hole) but it is not long enough to go thru the hole to lock. so when an M.2 is installed it is just dangling there...

Is this by design or am i missing something?

 

OMG! totally missed the identical pieces that do have a lock on them. :O
