What is the output of lsblk -f?

Edit: What distro are you using aswell?

There's uYouPlusExtra and YouTubeRebornPlus. I've never tried either though, so I don't know how good they are.

Ok.

My best guess is that something happened with the udisks daemon. A reboot will probably fix this. (G)parted probably doesn't use udisks, so that's why it kept working fine

Those letters and numbers are the partition UUID. Every partition has one and just used for identification.

That's what I was saying. Dolphin is getting info about partitions from udisks. Gparted is getting that info on its own. So if udisks is having problems, dolphin will have problems, but Gparted won't.

An option to hide a drive should show up when you right click on it
