Lightroom Classic: Sort by capture time bug (scans and raws)

Not sure whether this is relevant, but a similar problem occurs with scanned tiff images interspersed with camera taken pictures. In other words, scan some pictures as tiff and import Imp light room, then import pictures .ARW files, and then scan some more pictures as tiff. The new tiff images cluster with the older tiff files, and will come before the ARW files. In this situation there is no THM file.

The .thm sidecar file isn't the cause of the problem with the .mp4 -- it's a possible solution, since it contains the correct capture date expessed in local time, while the .mp4 contains the capture date in UTC (which is what LR is currently using).

Regarding your scans, a long-standing bug with photos not containing any metadata capture date (e.g. scans) was a fixed a few versions ago.  You can understand what might happening more easily by showing the capture date under thumbnails in grid view -- go to View > View Options > Cell Extras.  If you post a screenshot of the misordered thumbnails with the capture dates under them, that will make clearer what the issue might be.

I have attached a screen shot of misordered ARW and MP4 files.  The date and time are correct, but the sort sequence is wrong....

@ John...and here is a screenshot of a mixture of scanned (tiff) and camera pictures with the date/time showing...  the sort sequence is incorrect based on the date/time showing.  The data/time shown is accurate based on what I was doing.

Likely separate bug from the main thread.

Can you please upload to Dropbox some sample TIFFs and raws that aren't properly sorting? This was a long-standing bug in LR for years that was fixed a couple versions ago. It would be good to narrow down whether the old bug has resurfaced or this is something different.
