Cover Image is double in featured and text

Hello from Germany!

We have been using your WPematico tool for quite some time now. Unfortunately, the German translation is very bad, so you simply don’t understand some things correctly. Therefore here is my question:

I’m desperately trying to integrate our feed from one into one of our other websites. Unfortunately, it is not possible for me to use the cover image as ONLY the featured image. Each time the image is also included in the text. What am I doing wrong? I’ve already gone through so many options:

Can you take a look at the feed and give me a tip? Unfortunately it’s the same problem with all my feeds.

Best Regards

Thomas
