MF 360 Remote Hydraulics Malfunction

Quick disconnects still worked, one had a slight leak & I replaced it but that didn't help. I've got 5 Quick fittings, the four original plus the new one I bought. I've tried swapping them around & the malfunction is unrelated to the fittings. I usually use the two upper ones for lift and tilt and the bottom two for lower and dump. The bottom two are the ones that still work..If I hook the lift & tilt hoses into those two I can raise or tilt the bucket. If I hook the lower & dump hoses into them I can lower or dump.

Three point still works normally. The loader will still lift the front of the tractor off the ground if the lower hose is hooked to the bottom connector and if the raise hose is connected to the bottom connector, it will lift a load. Same with the pair I use for tilting the bucket (or for running the haybine) . I can switch hoses and bucket (or haybine) will go either way but it won't do both.

Suspect something in the remote splitter box that the loader hooks into but I haven't taken it apart yet, waiting for slower weather.

Any suggestions on what I may have fouled up?
