KH Master Firmware 1.69/1.70 Grid Import Current (hard limit 63amp) and Grid Charge Current (linked incorrectly) Issue

KH series firmware master 1.69/1.70 has an issue with GridImportCurrent not working above 63amps when previously able to work up to 80/100amps. On master Firmware 1.67 the gridimportcurrent was able to work beyond 63amps and import to house power say at 17+kw above 63amps, but now since 1.69 it can only grid import at 63amps/approx 14.7kw.
Also the "Grid Import Current" ie max current able to be draw from grid to overall supply of house(this includes inverter and other house electrical needs such as ev charger) and "Grid Charge Current" (Ie Battery max charge rate) are now linked on the inverter since firmware 1.69 on KH, this is an error.
If you update "= Grid Chg Cur =" on inverter (max possible is 50Amp) to 50Amp it updates "=ImportLimitCur=" to 50Amp which is an error as these are two independent settings. And if you update "=ImportLimitCur=" to say 80Amp it shows "=Grid Chg Cur=" as 80Amp on inverter screen, which in relaity is not possible as battery cna max charge at 50Amp, in error.
