Unity adding objects through script to scrollview (SetParent): Objects overlap

Question

I need to add X objects to a scrollview. I do it like this:

GameObject statsObject = Instantiate(instance.statsObjectPrefab);
statsObject.transform.SetParent(statsParent.transform);

statsParent is the content container if the scrollview.

Scrollview
---- Viewport
-------- Content // This is statsParent

In the pause I see that then objects are added successfully, but they all overlap and no scrollbar is visible.

The content has a content size fitter and a vertical layout group, but I tried now all settings and the result is always the same.

I use Unity 2019.2

From the Vertical Layout Group docs:

The Vertical Layout Group component places its child layout elements on top of each other. Their heights are determined by their respective minimum, preferred, and flexible heights according to [...]

You have to add a LayoutElement component to your prefab and set its values according to your needs.
