Solaredge battery reverting to default

I am trying to setup some automations for my Solaredge battery. Working with manual Select first to understand how it works. However, whenever I switch the battery to “OFF” so I can charge the car without draining the battery, after about 5 mins, either Home Assistant or the battery switches it back to “Maximise Self Consumption” and drains the battery. Anybody know why it switches back without my intervention? Thanks
