This is the new Nishijin. Everything is working well except for the middle tulip. Balls get stuck there and won't fall to the right like they should. You can see a ball stuck in middle photo. Nothing is wrong with the tulip itself. The only think I see inside the pocket is the arm that opens the side tulips. That moves and easily opens the tulips when I move it manually so I think it is functioning like it should, but it is the only thing I see there. You can see it in the last photo. Thoughts? Thanks
