When you update to 4.2.2 Android, the file system gets modified to allow for the multi-user environment. Essentially, /sdcard gets replicated into /sdcard/0. When you boot up and try to view your files, you can only see /sdcard/0 - but it appears as /sdcard (very confusing, I know).
I suggest you try using ADB to traverse your filesystem from within recovery (boot to recovery, attach USB cable, run ADB). If you know basic linux commands, this is easy, but basically run
to see the differences. The backups you made prior to the switch are probably in /sdcard/0/TWRP instead of /sdcard/TWRP. You can move them like so:
mv /sdcard/0/TWRP/* /sdcard/TWRP/
Then reboot recovery and see if they show up.
