ESS system going to passthru several times a day

I updated the ESS assistant in my two phase system recently to the (017A) version which I believe is the current version. Since I did that I have noticed that many times a day the system goes into passthru mode and imports power. See attached pic.

The system has 2 x 48/8000 Quattos running firmware 474. GX device is a Cerbo running 2.60.

I reloaded an older version that was a special assistant derived from the (0177) version which I still had on my laptop and it seems to have resolved the issue.

Is this some kind of bug in the ESS assistant or has something been introduced to make this happen?
