Solved: Fusion: Paint Tool is not saved

I made a little project, changed to the fusion tab and used the paint tool.
It worked and I could make changes in the inspektor.
I saved the project for later use.
Opening later, the inspektor for the paint tool is empty. The inspector says: <No Object selected>
The paintings are still there and can be deleted, but not changed anymore.
Is that behaviour correct? The Fusion Tool guide does not give an answer.
