How to pull blog text to paragraph settings


I can’t get the rich text from my blog post to appear in the short blog description under the headers. When I used the ‘get text from posts’ CMS area settings on the chosen paragraph I can only select ‘date published’ ‘blog name’ and ‘created on’.

I have gone into the CMS admin area and into ‘posts’ and added rich text and text to the CMS collection and it still doesnt show up. Please someone help me find a way for it to pull through some of the blog body text in the lorem ipsum area on the image attached!

Also if I try to individually edit or type in these paragraph sections, all the paragraphs change to the same text as if they are all linked.
