Not using a DE, I might not be much help, sorry. But you aroused my curiosity…

The 'Identify As" field corresponds with the name of the filesystem in your /etc/fstab file, just so long as the "UUID=" is part of the field's value, which you say it is. Using the /dev/disk/by-id entry instead for an external device may be designed to avoid the sort of problem shown by your sda2, which has no UUID.

As an emergency measure, you could chattr +i /etc/fstab to prevent anything changing it, while you investigate. You might even get some error messages occasionally, when some program tries to change it. Cheers, David.
