Interesting directory listing in Tahoe beta

I'm asking if this directory list is a problem:

As root I see _unknown as the owner of a script I'm working on in Visual Studio. This ownership is unexpected. Does it indicate a filesystem issue or my inexperiene with MacOS?

sh-3.2# ll
total 4
-rwx------ 1 _unknown 667 Nov  3 10:14 wpbackup.sh
drwxr-xr-x 3 _unknown  96 Nov  3 07:58 .
drwxr-xr-x 3 _unknown  96 Nov  2 09:06 ..
sh-3.2# exit

I recently did

sudo dseditgroup -o edit -a jeffreychimene -t jeffreychimene wheel

to write into /private/var/backups

Those files don't exhibit this issue:

 sudo ls -lat /var/backups
total 116108
-rw-r--r--  1 jeffreychimene wheel 101813175 Nov  3 10:32 20251103103246_wordpress_files.tar.gz
drwxrwx---  4 root           wheel       128 Nov  3 10:32 .
-rw-r--r--  1 jeffreychimene wheel   1121984 Nov  3 10:32 20251103103246_wordpress_db.sql.gz
drwxr-xr-x 39 root           wheel      1248 Oct 31 10:23 ..

As regular user I see the expected owner
