Current measurement is not lining up Batt vs multi RS charge currents

I looked for other topics but could not find any so i hope i dont create a duplicate.

When I look in VRM the charging current displayed by the batteries does not line up to the sum of the multi RS charging currents,

When compared to the solar generation (or grid import) it seems to be that the sum of all charging currents is correct (verified with clamp on current measurements Fluke).

Why is the value displayed by the batt incorrect and how do i fix it.

setup is

Battery Pylontech us5000C 8x

Multi RS 3x
