lightroom Classic .NEG and .JPG appearing despite option turned off

[merlinpi]

I shoot RAW and JPEG, and usually Lightroom classic only showed the RAW files. However, lately, i have noticed lately that both files appear as duplicate despite having the option turned off in preferences> general>treat JPEG files next to raw files as separate photos.

OS: Mac 10.14.6

Lightroom classic 10.2

any inputs or ideas?

First check that the file names produced by the camera are 100% identical (apart from their differing file extensions).

Otherwise if you don't want to see any JPG version within LrC, might you consider only importing the Raw files? (or, what I do, shooting either Raw or JPG?)

yes, I know I should only do RAW as this is what I use, but I kinda have those jpgs as absolute disaster backups (never had to use them) ... i do not have an issue of storage and i didn't have this issue of duplicates appearing on lightroom before.

I also checked any difference between the NEF and the JPG and didn't find any except the extension.

the odd part is that lightroom has the option of not duplicating those files, I use it (still do) but now it stopped working! hence i wanted to see if anyone else has this issue and how would resolving it be possible. thks!

Just a thought “out of the box” go to LrC preferences and select “treat jpeg files next to raw files as separate images”. Then quit LrC and reboot the application.

Go back to LrC preferences and deselect the option and reboot the application.

If that does not work then I would suggest resetting the LrC preferences.
