Some capture dates have changed and are now inaccurate

Some of my images seem to have had their Capture Date metadata mysteriously re-set, like a batch from 2018 that are now all 2006. The month/dates are also off, and when this has happened, they seem to always show up as just the first 2-3 months of the revised/inaccurate year. So if an image was originally imported as 10/12/2018, now it’s 1/18/2006. This has only occurred for a fairly small percentage of my images. Any help would be greatly appreciated!
