HTML not showing in page content

Dear community, I am bulk-generating posts with this great plugin but there ist one thing I cannot get to work properly: My prompts have some clear HTML and CSS instructions which are visible in the “preview” area of the plugin. If I create a post (or bulk-create many of them) those HTML and CSS stuff gets somehow lost in the process and the final post has none of them. Is there any way to approach this? I am using Classic Editor and Advanced Editor tools.
