I'm still back on 11.19 x 64. Today as a result of a failed backup I went to see if my backup drive was full. I also have Windows 10 set to backup file changes and having a large amount of data in that folder I was curious what was being saved. I simply tried to sort the column by the size and nothing happened. There were only 3 files but the directory showed way more bytes than I was seeing by looking at these files. At the folder level I also tried to sort to see if that was the biggest folder but no luck nothing happened no matter what column I tried to sort on or which direction. There's no padlock so it's not a locked format.
I finally out of curiosity went to my e: drive to see if it was something specific to my USB drive which is f:. I found a directory full of folders and again tried to sort on any column. Nothing doing. I switched directories to one with a smaller amount of files and again no way was anything sorting. I went into more of a user folder an attempted a sort and immediately it sorted. This is bizarre. I have never seen this type of behavior before.
One of the directories I tried sorting on F: F:\FileHistory\Todd\ASUSG73-WIN10X6\Data$OF I went to E:\Users\Todd\VirtualBox VMs which had two large files that wouldn't sort and I finally went back F:\FileHistory\Todd\ASUSG73-WIN10X6\Data$OF and tried again with no luck
So here's my windows user directory which says it's sorted by date but it's not:
