An Elevation Mark will show up in every Level that is shown in the Elevation View. You need to be careful of this because it may not be your intention to show the Elevation Mark (Bubble) in every view. The image below is showing an interior elevation on the right which includes just a small sliver of the Level above (Level 2) which means that the Elevation Mark is showing on Level 1 AND Level 2. Should the Elevation Crop Region have to cross the Cut Line instead of the Level to display? I think so.
