Multiplus ll not limiting AC current draw

I have a system with one MultiPlus-II 48/5000/70-48, a Cerbo GX, and Lithium battery bank with REC BMS. System was configured to limit current draw from AC at 10A 230V. This was working as expected for a long time. Suddenly one day the AC breaker tripped. After resetting the breaker i noticed that the multiplus it charging 3000W to the battery. I have tried several setting adjustments, but to no wain. Even whith Multiplus configured to 9.5A and running completly standalone it is charging the battery with 3000W.
Inverting from battery is not showing any issues.
Any suggjestions to what can cause this?

Firmware is updated to ver 500

Did you reprogram the system after the firmware update?

@Solan_G Do you have the charge power limited in the settings?

Do you have the charge current limited in EV Config?
