Hi Philipp,
As per https://help.salesforce.com/articleView?id=reports_historical_setup.htm&type=5, there is a limitation on the number of objects that you can setup Historical Trend reporting on.
"You can select Opportunities, Cases, Forecasting Items, and up to 3 custom objects. Historical trend reporting is available only for Collaborative forecasting, not Customizable forecasting. If Cumulative Forecast Rollups are enabled in Collaborative Forecasts settings, Forecasting Items are not available in historical trend reports."
Hope the above answer helped and appreciate if you can take some time to please mark as correct answer so others can benefit from it.
