LMS Course Outline

Hi there,

I saw on EDX platform the course outline its simplified into section -> unit
while in open edx in hawthorn version there are section -> subsection -> unit
how can I hide the subsection or section name and display it for the learner as section->unit

please, see this URL to see what I mean https://courses.edx.org/courses/course-v1:BerkeleyX+GG201x+1T2020/course/
it is showing section -> unit

how can I edit this or edit the code directly from the backend in which file specifically

any advise,
Thanks,
