Hi Kimberly,
You need to edit the actual file name.  For an example, one of your files has the name “IMG958069[2604].jpg“ and it appears that you have changed the Description.  The radiographs are all labeled “Mouse_Loveless_x” and that’s what needs to be changed.  The files are sorted on file name and the description is generally saved for additional information. 

Does that help at all?  It should be a fairly easy cut and paste to fix them all.
