How do i remove the text at the top of all my courses that reads "Lesson 1 of 9"

How do I remove the entire text?

This text is confusing for my technical courses, as we do not call each section a "lesson."

Additionally, I don't understand why this text is in a completely different font (it looks like courier). imo, not the best design choice to not have that text not align with the fonts I've chosen for the entirety of my course.
