Many flights with no positions on my station.

Why are so many of the flights I’m picking up not showing positions? Is that a hardware issue with the aircraft or my station? I know I’m not in a good place for MLAT but I was under the impression that ADS-B was intended for the aircraft to be able to broadcast their position. Is that not the case? Or will it be by 2020?

I’m also showing many more flights without positions as stated in this related post:
