When you use HTML section, the controls used for rendering content in list pages doesn’t support rich content (html) currently. The possible workaround you can try is to have 2 fields 1 with plaint text for the list pages and 1 with rich
content for de detail pages. So it may lead to the content not showing correctly.
If you still have any other question, you might share some screenshots so that we can review it and assist you better.
