This is the first report that I have seen of this problem, if it is a problem with LR or something else.
So I would first double check the Date/Time the camera is using. Making sure it is also set correctly for AM/PM. If the AM/PM isn't set correctly that could cause the images to go into different folders on import.
There are some longstanding bugs with time zone when importing that Adobe has chosen not to fix. But to know how to work around them, we'll need more details.
1. Which camera?
2. How are you importing: A USB cable, a card reader, or from your hard disk (e.g. if you copied the originals to your disk first)?
3. Select one of the originals that's been placed int the wrong date folder, upload it to Dropbox or similar, and post the sharing link here. We'll be able to tell authoritatively what time(s) have been recorded in the photo and how LR is screwing up.
1. Camera: Canon 5Ds and Canon EOS M6.
2. I Import from my local d: drive, with the following options:
- files are moved from d:\vide-cartes\[date of shoot] to s:\photos\_2018\ [date of shoot] (s is a locally attached usb drive)
- a second copy is made to i:\backup raws\2018\[date of shhot] (i is a network drive attached to a NAS)
3. Here's a link to one of the .cr2 pictures: Dropbox - 5DS_2136.CR2 , which should have landed in (...)\2018-04-28 but landed in (...)\2018-04-29
Thank you for helping!
- Pictures shot with my M6 behave the same way.
- I shoot in raw + jpeg. The pair of pictures allways remain together thus behave the same way.
- my LR catalog contains around 150.000 pictures.
