HELP EXPRESS FILES KEEP DISAPPEARING

This isn't about the Beta migration. That happened forever ago, but now for some reason all of my files are GONE. I can randomly search for some, but many were just "my project". I can't find ones from last week or two years ago. It shows some from yesterday and then some from the first week I opened the new Beta version and some from when I first set up this current subscription. The rest are simply not there in any folder under any of the sorting options. 

I cannot use this program if the files are unreliable, hard to find. PUT THEM BACK ALL IN ONE FOLDER they way we want them. Thanks. Including screenshot showing date jumps. 

If we are unable to find files from previous seasons or even last week this program is worthless and useless anyone other than college kids wanting nice insta posts. This is not reliable enough for fast-paced professional industries with files disappearing with each code update.
