SolarEdge migration from Domoticz

I switched from Domoticz to Home Assistant this week. I was able to transfer most things successfully. However, I’m running into an issue with SolarEdge. I migrated the historical data using this tool: GitHub - brjhaverkamp/Domoticz2HomeAssistant: Migrate data from Domoticz to Home Assistant, and that worked fine. But later, on the first day after the migration, a large negative value was added, equal to the total yield of the historical data. Any idea what might be going wrong?

Anyone have any ideas?
