Convert into blocks

Hi all! I do not understand why inside the sample course on Rise360 (titled "Employee Health and Wellness (Sample Course)") there are some funcion that I do not find if I create a new course by myself!

I.e.: under the lessons menu, appears the tipe of lesson (timeline, process etc.); and again, if enter inside timline lesson, i find, on top, some round dots numbered, one for each part of the timline, and I read "convert to block".
