Each settings section is clearly separated out with bold heading and a border:

The "Common settings" list content common to every step - such as the title for the step and the task instructions.

If the step is a reference step then it will have a "Library item settings" section. This section varies depending on the step type.

If the step is not a reference step it will instead have settings for the type of step it is (in this example it is a multiple choice step).

Additionally if like this example, it is an apply step then the default instructor response setting is also shown.

And also, if it is and apply step and there is at least one reference article for this course, then there will also be the optional "References settings" available.

At then end you will find the "Optional settings" - such as student points amount. Optional settings only show as applicable and if for example you have turned off the student point option (see article Student points) and there are no other option settings applicable, you will not see this step at all.
