Shopware 6 Custom CMS Block | Fronend rendering

Hey,

i followed this tutorial to create a custom CMS Block in Shop ware 6:

Create CMS Block

So know I got the custom block which I can use in the backend but when i save it and switch to the frontend the component only shows the outer divs and no content will be rendered. However i can set background color, classes and margins in the backend.
Maybe some of you know what omegle.club I did wrong and can help me. I’m rather new in the shop ware developing scene.
