I appreciate you arriving with a response so quickly.
Solution: I made a copy of a rich text element and unliked it, just like you suggested. I found that the rich text is comprised of all bunch of individual H1 H2 and paragraph (and other) elements, that make the rich text - rich text. The problem was 2.3 REM spacing at the bottom margin of the paragraph. I removed it in the unlinked copy of a rich text, and it reflected on the dynamic rich text element.
