Force Charge rates and breakers

I am new to the FoxESS world and have recently had a KH10 inverter and 42kWh battery installed to pair with my existing 14.6kW solar panels.
When I set the inverter to force charge at the 10kW rate, I am seeing on the FoxCloud app up to 15kW coming from the grid.

Last week the breaker between the inverter and the grid tripped during this charge time.
I had the installers come back to look at it and the breaker was 40Amp instead of 50Amp so they changed it.

However I am not see the 15kW import and wondering why it gets so high?
Is it that the 10kW setting for force charge is the amount going to the battery, not what the inverter pulls?

This would make sense at the moment as I have a house load of 5kW and can see 11kW going to the battery and have 1kW coming from the panels.

Is this all going through the 50Amp breaker between the inverter and grid, or is only the 10Kw that is set going through it?
