DESS is showing strange behavior: charging from the grid on the most expensive times

Dess starts charging from the grid in the morning and in the evening at the most expensive times… It is running on green mode, but shi behavior is NOK I strongly believe…
Charging the battery to 100% happened yesterday already, so that should not explain it.

Here is looks odd as well. With charging and discharging at the same hour
