Goodwe_grid_export_limit and slider in home assistant for Goodwe inverter device doesn't work

Hi home automation experts,

I have a Goodwe GW10K-MS-30 inverter, the inverter is already on latest firmware. I recently installed home assistant green and setup my Goodwe inverter integration in home assistant. All the sensors/numbers are visible and refreshing ok. Only thing at the moment that doesn’t work is when I adjust the number.goodwe_grid_export_limit; the slider for grid export limit in home assistant also doesn’t take any effect.

Anyone else have had similar problems? Are there some other setup required to get this grid export limit adjustment working in Home Assistant?

Thanks
