Solved! by bvm76. See the answer in context.
It's probably you have your level set to survey point and the link model is set to project base point or vice versa.
I don't currently have a revit machine right now so instruction may be a little bit off.
1. Click on the level and open the properties dialog box.
2. On the property dialog box click "Edit Type".
3. Constraints-> Elevation Base -> Change Project Base Point to Survey Point or vice versa.
