Weird directories in /mnt

Hi everyone. I am rebuilding my TrueNAS setup from scratch and I encountered a weird thing: I have a single pool, pool1, but when I list /mnt I get two more directories that appear to be the pool name plus a timestamp, as below:

admin@nas01-dellt40[/mnt]$ ls -la                                                       
total 33
drwxr-xr-x  5 root root  5 Jun  3 12:43 .
drwxr-xr-x 21 root root 31 May 29 17:24 ..
drwxr-xr-x  8 root root  8 Jun  1 20:41 pool1
drwxr-xr-x  3 root root  3 Jun  1 20:04 pool1-0dfa-2024-06-01T12:04:17.473057
drwxr-xr-x  3 root root  3 Jun  3 12:43 pool1-5bc5-2024-06-03T12:43:10.733431
admin@nas01-dellt40[/mnt]$ ls -la  pool1-0dfa-2024-06-01T12:04:17.473057                
total 10
drwxr-xr-x 3 root root 3 Jun  1 20:04 .
drwxr-xr-x 5 root root 5 Jun  3 12:43 ..
drwxr-xr-x 2 root root 2 Jun  1 20:04 ix-applications
admin@nas01-dellt40[/mnt]$ ls -la  pool1-0dfa-2024-06-01T12:04:17.473057/ix-applications
total 1
drwxr-xr-x 2 root root 2 Jun  1 20:04 .
drwxr-xr-x 3 root root 3 Jun  1 20:04 ..
admin@nas01-dellt40[/mnt]$ ls -la  pool1-5bc5-2024-06-03T12:43:10.733431 
total 10
drwxr-xr-x 3 root root 3 Jun  3 12:43 .
drwxr-xr-x 5 root root 5 Jun  3 12:43 ..
drwxr-xr-x 2 root root 2 Jun  3 12:43 ix-applications
admin@nas01-dellt40[/mnt]$ ls -la  pool1-5bc5-2024-06-03T12:43:10.733431/ix-applications 
total 1
drwxr-xr-x 2 root root 2 Jun  3 12:43 .
drwxr-xr-x 3 root root 3 Jun  3 12:43 ..
admin@nas01-dellt40[/mnt]$ 

These directories contain no data.

For context, the pool configuration is the following:

I guess it could have something to do with ix-applications not being encrypted, but I really have no idea. Any help in understanding why this is happening would be very appreciated.

I’m running Scale 24.04.1.1
