Why is CoursePress not working properly?

Hello! I tried using the free version of CoursePress and have encountered a similar problem in CoursePress Pro. When I try to add an element to a course unit, it does not work properly. For example, to add text, there is a field that seems to be set to not be visible. Even after changing that setting, it seems that it doesn't update properly. Please take a look at the link below.
