Corrupted, incorrect preview showing in Lightroom Catalog Library

  • Updated 2 months ago
When I load images into my Apple computers (both a MacBook Pro and iMac), a random image from an earlier card appears in the catalog in the Library mode.  (I "show in finder," and that takes me to the correct and actual image).  When I switch to the Develop mode, the proper image appears.  If I go back to Library, the errant image appears.  If I duplicate the image, the incorrect image appears as the duplicate, too.  This has been going on for a long time (over a year)...I keep hoping that an update will resolve this, but it hasn't.  Please help!

Reset your preferences:

A Preference File will survive a Lightroom uninstall/reinstall. Sometimes weird behavior is corrected/cured by resetting the preferences.
Reset Procedure:

1. Close Lightroom.
2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom.
3. Overwrite the Preferences when prompted by the dialog.
4. Close Lightroom.
5. Restart Lightroom.

Does the issue continue after resetting the preferences?

I will do that...  But, first please let me know if that will reset anything.  That is, should I save some or all of my settings?  Will my entire catalog of previews need to be rebuilt, etc.?  Thanks SO much.

It's not a biggie, took me 5 minutes to check the Classic Preferences, only a couple of things had changed, as I recall.

You will find some menu options and the location of your backup catalog will change but little else.  It takes you back to day one and shows you some of the onboarding screens too but they are easy to dismiss. 

This article explains it in detail: https://www.lightroomqueen.com/how-do-i-reset-lightrooms-preferences/

Before you do that just try making a Develop edit and then going back to Library and zooming into 1:1. That may refresh the faulty preview.

Thanks much!  I will try the preference uninstall/reinstall.  But, first I tried Victoria's suggestion.  I did it twice--one time, I changed the image from color to black and white and went back to the Library and zoomed in 1:1.  That worked!  Then, I reset it and tried it again after just changing the clarity to random (and going back to the Library and zooming).  That worked, too!  Wow....  The only small issue is that the image does revert back to the wrong one if I undo the edit and go back to the Library.  Both are very good suggestions.   I will use them both...Rikk's does seem like it might be a fix while Victoria's is a patch.  Either way, they are both welcome adjustments that seem to fix this annoying problem.  Thanks again.

Have you tried a different memory card? SD memory cards have a high failure rate, one of the reasons that we need to move to CFexpress. If other cards work, my recommendations:
  • recycle the card 
If you want to try to make it usable, though I personally wouldn't trust it, perform a true format and TRIM operation on the card.
  • format it on your computer as this will properly reconstruct the low level file system. Some day cameras will do this correctly.
  • formatting it in your camera
  • see if the problem still exists
Tip: NEVER use the erase function in the camera. Always clear the card with the FORMAT function. Erase, with single files or for the whole card, leaves behind pointers and partial files. Even on a computer, Erase is a bad idea but it is a terrible idea in a camera.

Thanks for the tip about the cards, but I am aware of that and I use safe practices.  Also, when I first started encountering the issue, I even changed cards to see if the problem was unique to a particular card or something.  And, I downloaded images from my laptop (as a catalog) to my desktop and the problem even carried over from the laptop to the desktop! 
Hopefully, one or both of the suggestions above will work effectively.  I'll check tomorrow.
(Hard to believe...I never heard of anything like this happening to anyone else.)
I appreciate your input!
