Solved: Energy harvested get shown negative all the sudden

Hello everyone…
I was using a smart plug to measure my energy production of my pirate solar system.
Due to construction, i had to take it down in august but finally got it back up and running.
But for some reason, the energy screen shows only one high negative bar per day instead of the typical positive pyramid shaped “curve” over the day.
Outlet itself seems to see it correct.
Any ideas?
Will try to get pics added in a minute…
