The Collector Problem

[PerpetualAscent]

I'm trying to complete The Colelctor but it won't let me continue. I found a statue, sold it, was taken to Umbacano and got the quest. Then I found another couple of statues and tried to sell them to him but it won't let me. When he asks me if I have more statues for him, the only option I get is to say no. So I went and got all of the other statues, so now I have nine, and still no luck. So I can't continue the quest, and I can's start Nothing You Can Posses. I tried advancing the quest with the console but it didn't work.

Has anyone had this problem and been able to fix it?
