Did not get what exact is the issue within Lightroom?
Which version of Lightroom are you using?
If possible, share the workflow steps precisely and the screenshot of the exact issue.
"Delete. Then renumber." I don't understand.
Sorry about the confusion. I am really frustrated as this issue has just come up in the last two months. When trying to fix it I have quit LR, and sometimes it magically corrects itself. Sometimes it has not.
Using LRCC on Macbook Pro Operating System OSX10.10.3
I import pictures. Do an edit and delete from LR the "X" images. Then go back into Library select all remaining images and F2 (Rename Photos). After that is done, return to Library. Then the magic happens - sometimes the pictures are in order and sometimes as I look at the filmstrip an image will change to a deleted image. Sometimes it will switch back and sometimes it will not! If I go to the metadata the metadata does not jibe with the capture time either. When trying to fix it I have quit LR, and sometimes it magically corrects itself. Sometimes it has not.
Delete your Preview cache.
You can find this cache, it is a folder whose name ends with Previews.LRDATA, it is in the same folder as your catalog. Delete this Previews.LRDATA folder. Do not delete anything else.
Thanks. I will give this a try.
Have run a test import, deletion of selected photos, and renamed. Seemed to go well.
Thanks very much. Really appreciate your expertise.
