I've just been looking through my library in Lightroom CC and noticed some things out of order. I've sorted by 'Capture Date' and there seems to a bunch of videos with the exact same capture date and time that were actually all taken on different dates. I've searched in my Lightroom Classic library, and they display correctly on their original dates.
So this seems to be a bug with CC. These were all migrated from the Classic catalogue.
