I think that is because the section cut lines represented as polylines with width, so lineweight settings have no effect. You need to edit polylines (in yellow) and assign zero width to them - you can do this via properties inspector or with PEDIT command with multiple option (in order to edit them all at once).

After assigning zero width you will be able to assign lineweight to the section lines via Layer or individually.

About the second question: what do you mean about "visually smaller"? Why did you decide it is smaller?
