Tibber Integration

Hi all,
I am using Tibber on my HomeAssistant:
Home Assistant 2023.9.0
Supervisor 2024.02.1
Operating System 10.4
Frontend 20230906.1 - latest

My issue is that there is no negative numers on my current consumption sensor. Heavily needed for my solar panels and power balancing for the EV car charging station.
Am I doing someting wrong? Is there a fix I do not know?
