Missing Charge/Preconditioning Session when preconditioning is using more power than charger delivers?

Here i am missing a Charge that happend on 25.01.2021 15:45-16:01.

In this time i had preconditioning on and the charger was connected. It even showed as charging in Teslafi and the Raw data is correct too. But I assume since the charge wasn't adding anything (only 4kW charger) it isn't showing it at all?

Also i assume this isn't showing up in the summaries and therefore is not calculated in charging cost?
