Shuttle SSD Dual Cartridge not recognized

Got 2 Dual SSD cartridges from a G Drive TB3 SSD unit into my G Drive Shuttle EV unit,and the system only recognises one SSD when inserted. (The left one)

I believe we’re going to need you to contact us directly for this one. I’m having trouble picturing exactly what you mean in this situation.

I just called no answer. I called and tried to discuss on Friday.
