KH10 keeps resetting Export Limit to zero

I have a recently installed KH10 and three times now the export limit has reset to 0 kW.

I can change it on the front panel or ring Fox ESS, but this is a real problem as I am away from home. I wanted to export this morning before the grid price went negative, but now have a full battery and will export at negative price.

I only have the app, and cloud connection to Home Assistant.

Version_Master: 1.58
Version_Slave: 1.02
Version_ARM L 1.58

You may need to upgrade to local Modbus for your Inverter/Home Assistant control.

I am new to HA, but maybe you can set the export current/power via that.

I found out Amber was doing it. I have put a logged it with them.

Yes I am trying to get the modbus set up, but am having problems. I have a modbus RS485 to Wifi adapter that I have used previously with no problems, but I am getting nothing on it. I suppose this is a whole different discussion.
