I usually don't change my Cut Plane Settings unless there is a special reason to do it. And unless I'm missing something, I don't see the need to change it in your case.
I can think of a couple of reasons why your element might not be showing on plan:
- It is placed on a wrong Story: in your case, make sure it says "Home Story:0" in the Settings when you select it.
- You have wrong Floor Plan Display settings for the element
As for the Stories, they shouldn't be a problem.
