Disk not showing as mounted in KDE Dolphin

I have two sata ssd's formatted as btrfs RAID1 that I keep my virtual machines on, mounted to /vm using an fstab entry. It seems to line up with when I added a 3rd sata ssd for something else, that my /vm mount no longer shows as mounted in Dolphin, but on terminal I can confirm that it is mounted.

The device is definitely there at boot time:

$ findmnt --real
TARGET               SOURCE                     FSTYPE      OPTIONS
/
.....
├─/vm                /dev/sdb1                  btrfs       rw,relatime,compress=zstd:3,ssd,discard=async,space_cache=v2,subvolid=5,subvol=/
.....

And I can open and run the qemu vm's that reside on it.

When I click on the device in the "Devices" list in Dolphin, it prompts for password, I enter it, but nothing happens.

If I check on terminal again after clicking it in Dolphin, this shows up:

$ findmnt --real
TARGET               SOURCE                     FSTYPE      OPTIONS
/
.....
├─/run/media/aaron/VMs
.....
├─/vm                /dev/sdb1                  btrfs       rw,relatime,compress=zstd:3,ssd,discard=async,space_cache=v2,subvolid=5,subvol=/
.....

If I keep clicking, I keep getting more entries appearing; VMs1, VMs2, VMs3 etc.

$ btrfs device stats /vm

reports 0 errors on the array.

Filesystem looks ok...

$ btrfs fi sh
.....
Label: 'VMs'  uuid: 33b21784-8b86-45d5-afb7-94b5f33041d1
    Total devices 2 FS bytes used 106.58GiB
    devid    1 size 232.88GiB used 129.03GiB path /dev/sdb1
    devid    2 size 232.88GiB used 129.03GiB path /dev/sda1

The fstab entry:

UUID="33b21784-8b86-45d5-afb7-94b5f33041d1"     /vm     btrfs   compress=zstd:3 0 0

I've never seen an addition to fstab screw up an entirely separate mount like this, so I'm thinking this is a KDE/Dolphin bug. I'm seasoned well enough with terminal but new to Linux desktop so not sure where to start with this one
