Skylla-IP65 12/70 (1+1) and Skylla-IP65 12/70 (3) not charging together

I have 2 Skylla-IP65 12/70 that do not output 140A of charging as expected on my 12VDC system

I am interested in what I should be seeing or if I have an issue with the configuration below.

When the batteries are at 13VDC The 1+1 charger will go to 60-70A of charge while the (3) charger will hover around 6-8A of charge. This is far short of the expected 140A of total charge I should be seeing.

The chargers appear as a single charger when displayed on the Cerbo, this appears to be by design.

I have the following.
A Skylla-IP65 12/70 (1+1)
A Skylla-IP65 12/70 (3)

Devices are in a cool environment and are cool to the touch.

Both are connected to a Cerbo via VE.CAN in this simple config:
Cerbo — UTP-8 — Skylla-IP65 12/70 (1+1) — UTP-8 — Skylla-IP65 12/70 (3) — Terminator.

Settings are in table below.
