Home Battery -> Victron discharged blocked by "keep 99% charged"

[hanvanvilsteren]

I have a Victron ESS set up, and most of the time it works flawlessly. However, yesterday I noticed that no matter what settings I changed, the home battery refused to discharge or help charge our Fiat 500e. In Victron VRM, under Settings -> ESS, I saw that 'Minimum SoC' was set to 99%. I definitely didn't change this myself, so something within the ESS must have triggered this restriction (which might be intended behavior under certain conditions, but it stayed stuck at 99%). It seems like it might be a bug. Once I manually adjusted the Minimum SoC back to 10% (in VRM), the home battery immediately started discharging and helped charge the Fiat 500e again. Any idea what to do?
