files not reflecting xmp status

For awhile now I have been seeing that raw files that were processed in camera raw, cropping and exposure are not showing up in Bridge.  Usually if I just reopen in CR and come back to Bridge, they recover and display as they should.  But now I came across 4 pictures that are very dark and uncropped and went to CR and back and they remain the same.  In CR they are cropped and with good exposure.  I went back and made a slight temperature change, as sometimes this stimulates a return to the corrected status but now that isn't working either.
