Hi,
For bullets on single unit please add this code in appearance>> customize>>custom css
.single-unit #unit_content .course_content_content ul {
list-style-type:disc !important;
padding-left:25px !important;
}
.single-unit #unit_content .course_content_content ol {
list-style-type:decimal !important;
}
The image appearing below is an issue for which I'll create a trello card and share the link with you.
