The trick is with the Home Story Setting and Floor Plan Display setting of Show on Stories (Cut plane affects this but it is a different situation). If you want to show a wall in a specific floor make sure that Home Story settings is Set to the appropriate story and that Floor plan display is set to Home story only. If you set the wall to automatic AC will decide were the wall should be shown provided that the Floor Plan display is set to All Relevant Stories.
The problem you might have now might be is that you have;
1. Home story set to First Floor or a specific one that it is not the sub basement or automatic
2. Show on Stories is set to - Show on Home story only
This translates to a wall that should be shown on the first floor and that in 3D space is in the -1 level therefore it disappears from the floor plans though it is still shown in 3D and changing the height will not do anything about it. This is a very rough explanation. To fix this one you can do either, change the Home story to automatic or Sub level, or change the show on stories to all relevant stories.
