If you are opening the elevation viewpoint (or right-clicking the marker and opening -same thing), then either the marker is not including your building in its range: either the marker is facing away from the structure, or you have the vertical height limits or horizontal depth limits of the marker set in such as way that they do not include your building.
If you're opening the elevation from a view in Navigator (assuming then that you either created the view, or are using a template with pre-defined views), then it could still be the issue above, or the view's saved layer combination might not include the layers onto which you modeled your building.
