On some photos in the library module an exclamation mark appears and they do not embed the changes made in the developer module. Then one toggles with the Developer module and goes back to library and the images loads the changes made in develope module (but the exclamation marks remains).

HI there! Thank you for reaching out! Could you please share a screenshot of the issue you're experiencing? This would help us gain a clearer understanding of your situation. 

 

At first glance, this appears to be a preview-related issue. Try this:

1) In the Library module, press G for Grid View and select all the affected photos.

2) Now, click on Library (at the top) > Previews > Build 1:1 Previews.

 

If steps (1) and (2) don't solve your issue. Try rebuilding all the previews. 

-Click Lightroom Classic > Catalog Settings.

-Once the settings window is open, click the General tab and then the Show button to open the folder in Finder.

-Look for a file/package named: [Your Catalog Name] Previews.lrdata.

-Rename the entire package file (e.g., from Previews.lrdata to Previews_OLD.lrdata) or simply move it to your Desktop.

-After renaming/moving and restarting Lightroom Classic, it will automatically create a brand new, empty Previews.lrdata package in the original catalog folder.


Hope this helps!
