I'm having the same issue. I unlocked 5 hard drives before checking the hub, and noticed 2 that I was sure I didn't select. Today I researched 2, the first one I chose the first option as it was what I wanted, the second I had a choice between steel screws and Caterium computer, I selected the computer. When I checked the hub it was "expanded pocket dimension" needed modular frames and cable. Definitely not one of my options, but interesting.
