Dc to Dc 12/48 in bulk no current pull

Hi all

I sit with an issue where when my Sprinter is running the dc to dc 12/48 go to bulk and voltage reads correct but it is not pulling current to charge the batteries.

System:
2x pylontech us5000
Multiplus 2 5kva
Orion dc to dc 12/48 8a
Lynx (basic)
Shunt (set as dc monitor between batteries and load)
Everything connected to lynx on load side of shunt. I also disconnected solar so it does not take priority.

Used clamp meter to confirm.

See images for settings on Orion.
