Whats this in the lower DU

That's not the Lower DU but the inboard DU, David ;-)

Although it should have been Lower Center DU.

What you see on the Navigation Display (ND) is the Vertical Situation Display (VSD) of the GPWS system, it will be visible in the MAP mode of the ND if you push the CTR push button twice.

 

The VSD depicts the vertical situation of the airplane relative to the terrain throughout all phases of flight. The VSD also depicts the vertical situation of the airplane relative to the runway during final approach.

Perhaps some what off topic, but I recently noticed that the -900NGX has a third MFD button for the LDU, it seems to be inactive, but what is it for?

It's cancel/recall button for fail-operational autoland. It will recall autoland status eg."NO LAND 3", "NO AUTOLAND".
