I agree with Chris - looks like the cork has fallen off the key, based on your picture. There should be a sliver of cork between the bottom of the adjustment screw and the metal keywork at point "C" in Chris's photo.
You say you don't understand why the key should lift off when you press the D key? The reason is, it is designed that way.
This key is the "Forked F vent" - it is designed to open only when you finger Forked-F, and otherwise to remain closed. This is achieved by opening it when your RH ring finger is depressed, and closing it again when you depress your middle finger.
If the adjustment is out of whack (or if the key-cork drops off) your middle finger will not close the key but will leave it a tiny bit open. If you over-adjust, you can leave a gap under your middle-finger key and also under the small key between your index and middle-fingers. Getting this just right is hard.
