Turn off cloud sync for Skyrim and see if that helps. Also, your title could use some work.
"Saves not showing in menu" or something is a bit better.

Edit:
I just saw your second pic. You see the .tmp after the .ess in the file name? That's the problem.
.tmp is for temporary files. Now we just need to track down what is doing that.
First off, try renaming those files and just delete the .tmp. Make a backup of those files (with the .tmp in place) first just in case things don't go too well.
