Hi @zerotoone.de ,
Thank you for reaching out to us. This usually happens when there is an invalid html code with orphaned or a missing a closing tag, please check your content and look out for a missing tag and close it.
In your case it looks like it's the
<p> tag that is left unclosed which is wrapping other elements as well. Check your content carefully and close all tags properly to fix the issue.
Let us know how this goes!
