Wrong coordinate values of element bounding box

Hi. Why do I click on an element on the 1F to create a bounding box, but the z-coordinate value of MinPoint far exceeds the elevation of the 1F?
And all the elements in this model seem to be like this… But if I put the elements in other models, I can get the correct values.
The strangest thing is that it can be found in RVT that MinPoint is in the correct location.

This is my first time encountering this situation…The file is at the bottom.

There is no error, the location of the points is correct

“If the Elevation Base parameter is set to Project, the elevation is relative to project origin. If the Elevation Base parameter is set to Shared, the elevation is relative to shared origin which can be changed by relocate operation.” Revit API Docs

The bounding box of an object is given in model coordinate system (Project Base Point) values

Check if you have shared coordinates used in your model and your levels elevation base parameter settings
