Main UR5e checked. Fitted adapter present. Spare kit absent after forty days of next shipment. Apparently the fitted one is doing double duty in their paperwork.
Then have them state that partial offer clearly. You might choose to receive the plate, but it should not close the kit line or turn an incomplete spare into available stock.

Requested. Seller's credit covers the complete missing contents, but replacement availability is still being checked. Not choosing from another catalogue promise.
