Posts thumbnails are not displayed after pulling feed

Hi,

I am using the lite version. I want to get post from one wordpress blog to another, both are mine. The plugin is working, the only problem is I can’t manage to get thumbnail images, it pulls only the content.
On the feed site https://www.thorsten-schuell.com/feed for each post there is one featured image that is for thumbnail, and I would like when I pull the feed to get the posts with that images.
I watched the videos that are uploaded tried the settings, tried and different settings as well but it doesn’t work. Could you tell me how to make it work please?
