Link to block device

Double-clicking on Home, then File System, then dev, then disk, and finally label brings
up a list of the links to the various Data partitions:
/dev/disk/by-label/1pt8TB-Data
/dev/disk/by-label/Data-0
/dev/disk/by-label/Data-1
/dev/disk/by-label/Data-2
/dev/disk/by-label/Data-A
/dev/disk/by-label/Data-B
/dev/disk/by-label/Data-C
/dev/disk/by-label/Data-D
/dev/disk/by-label/Expansion
/dev/disk/by-label/GBData
each of which is a link to the particular block device,
the first four of which I created this morning with the following sequence of commands:
sudo ln -s -T /dev/sde2 Data-0
sudo ln -s -T /dev/sdb3 Data-1
sudo ln -s -T /dev/sdd3 Data-2
sudo ln -s -T /dev/sdc6 1pt8TB-Data
sudo umount /media/george/Data-0
sudo mount /dev/disk/by-label/Data-0 /media/george/Data-0
sudo umount /media/george/Data-1
sudo mount /dev/disk/by-label/Data-1 /media/george/Data-1
sudo umount /media/george/Data-2
sudo mount /dev/disk/by-label/Data-2 /media/george/Data-2
sudo umount /media/george/1pt8TB-Data
sudo mount /dev/disk/by-label/1pt8TB-Data /media/george/1pt8TB-Data
I cannot reconstruct how the other six found their way into existence.
If I execute the final four pairs of unmount/remount steps one-at-a-time,
I can watch them disappear and then reappear on the Desktop.
Waitaminnit ... they each reappear with the same incorrect device name as appears in the
side pane of the GUI Home folder as shown in the attached screenshot, wherein the ten red
triangles indicate the Data files that are displayed on the Desktop. Two of the Data partitions
are labeled 958 GB Volume, but on examining the Properties of each, it is clear that they
ought to be labeled Data-1 and Data-2. The names under Devices in that side pane really
have to be corrected; I need to find out where that side pane is coded so that I can correct
the problem.
