Lightroom warns that files have different names when relocating Missing Files
I had previously moved a couple of catalogs and their images onto my NAS in order to temporarily free up some space on my computer. I moved the main folders that contained the catalogs and the images all together. Today, I just needed to access those catalogs again so I moved the folders all back to where they originally were.
Now when I open the catalogs I get asked to upgrade so I do but then all my images show up as missing. And when I try to relink a file I get the following warning (see images below)


Do you have any ideas as to what is causing this? The file names look identical to me. Thank you.
