Multiplus 2 stays charging in bulk when batteries are full

[Godart]

I have setup a small ess system to be able to store some daytime power to be used at night. The system consists of a multiplus 2 48/5000, cerbo, 4x12V 100ah lifepo4 batteries with build in bms (safety only no comms), a lynx smartshunt and VM-3P75CT energie meter.
when I connect the meter and there is surplus solar power the multiplus switches to bulk charging even when the batteries are full trying to keep the total of three fases to 0 amp.
I have not been able to find the setting to stop charging the batteries when 100%

Does anybody know what i am doing wrong?

Charging is based on voltage not SOC.
It charges in bulk until the configured absorption voltage is reached.

Ok where can I configure the absortion and float voltage? I already lowered the max charge voltage but that did not help.
