Did you generate these STLs in an earlier version of Slicer?  
If so, Slicer recently changed to using LPS coordinate system for 3D Models: [Model files are now saved in LPS coordinate system](https://discourse.slicer.org/t/model-files-are-now-saved-in-lps-coordinate-system/10446).

If you expand the Load Data dialog box options, and change the Coordinate system from default to RAS, perhaps that will fix it.
