I've just recently purchased Onedrive and have backed up all of my photos. However, over the passed couple of days I have noticed that hundreds of old photos are suddenly appearing with the current date. 

Recently, it uploaded over 200+ photos which I've taken over the years and uploaded them with yesterday's date 1st February 2021. I also have Google Drive however do not have this issue with their photos app. 

Do you know how to fix this?
