GoodWe Inverter Settings - Not showing second battery data

I’ve got a bit of an issue with the GoodWe Inverter (GW6K-EHA-G20) we have installed.

Data is coming through fine but everything in Battery 2 is 0 / has no data.

I’m using the GoodWe Inverter HACS (Experimental) integration: GoodWe Inverter Version 0.9.9.30 with data coming over Port 502 TCP. See integration here: GitHub - mletenay/home-assistant-goodwe-inverter: Experimental version of Home Assistant integration for Goodwe solar inverters · GitHub

From what I can see on Github this issue has existed previously.

Does anyone else have this problem / know how to fix it?
