Part of my new images are shown as already imported (under a wrong date), why?

[DoggographerZ]

So, this is my "work"flow:
I take some pictures, I take the SD card from a camera, into m1 air, copy it to a folder on a hard drive. I open lightroom AFTER that (I keep it closed until I copy the images because the import dialog resets my import view, and I'm lazy :D) . When I open lightroom I notice (for about a month or so?) that about half of the new images are greyed out as they are already in the library. If i search the library folder for filename, I can find them somewhere in the middle of a 15k folder (where new images should be on top from number 1 ascending) numbered around 8000, and if I open them in the develop tab they all seem to have the same import time and date ( 11.11.22). 

Now, I know I didn't invent time travel yet and I didn't (again, yet!) go and import the freshly taken photos 4 months ago, so does anyone have any idea what could be the issue, and how can I get LR to let me pick what pictures I want to import?
When I first noticed this a week ago, I did go into cannon imaging whatever app, and disconnected the lightroom sync, but it didn't make any difference.

• Does this occur if you use a new SD card, or at least one that has been formatted in camera, before the shoot?
• During Import, do you select add, or Copy ( your workflow imply Add, would be surprised if Copy)

Can you expand on that? What happens? Perhaps a screenshot or a video capture?

After poking around for the last two days, I think I figured it out.
The first clue was that the metadata of those images was all wrong. Reporting a different lens and rotation, as well as in-app ratings.
So, I move 'old' images from the 'working' folder (the one described in a post) to an external hard drive. My camera, after reaching 10k photos in a folder makes a new folder for the next batch, but the filenames actually remain the same as the previous batch, so when I tried to import new images, it recognized the filenames from 10k pics ago, and just filled them in those old edits and data.

Regarding this, usually, when i click on the import button it's already opened up to that one working folder. When I plug the sd card in, the import dialog pops up, i close it, and the next time I open the import dialog, I need to click all the way through the desired folder. But, that's not an LR issue, that's just me being lazy, and Ijust used it to point out why I could not import the photos earlier by accident 🙂

You have sort set to OFF.  Change it to Capture Time

Ahh.

Consider two possible workflow changes

• In camera, in settings, in file settings, change the file name syntax.

or

• In computer, copy the images from the card to the hard drive. Use your computers OS to batch rename them.
