gray and black tanks levels

Rate this Entry
After draining all tanks,(two for gray) the black still shows 1/3 and the kitchen island shows the same. This is a 2017 Reflection. At times, the gray kitchen smells like the black. Should I just leave the Gray#2 open all the time? I'm a new camper/owner and any help would be appreciated.
