I took everything out, I took out the small white plastic insert that went into the rubber seal, there was not one in the one that came out of it, and reinstalled the parts. I positioned the stem with the part that stops the extender from going past that point (the range of movement of the handle if that makes sense), anyway, that piece is on the outside side...if that makes sense. Turned the water back on, and I can turn off the water, but I have to turn it toward the off then bring it back a little in order to turn it off all the way. If it is turned all the way off, I can hear the water running, and it is a constant drip. So I am close but still not completely right.
