Before/after-snapshot-root action isn't reflected in server UI after being set via CLI

Kopia 0.17 that's installed in server mode on Ubuntu 23.04.

I'm trying to configure the Kopia via Ansible and Kopia cli and struggling with the 'policy set': kopia policy set "user@host:/some/path" --before-snapshot-root-action "/path/to/script.sh script-param1 script-param2"

After running the above command and looking at the Kopia UI policy page for the 'user@host:/some/path' the 'Before Snapshot' field (both defined and effective) remains empty no matter what I've tried although the 'kopia policy show ' shows that the before action is correctly set:

Run command before snapshot root:           (defined for this target)
  Command:
    /path/to/script.sh script-param1 script-param2
  Mode:                         essential
  Timeout:                           1m0s

On the other hand, if I set the same script but on the Server UI manually it is set correctly and visible in the UI and the snapshot runs successfully. But the kopia policy show shows it as an embedded script (not as Command as shown above) :

Run command before snapshot root:           (defined for this target)
  Embedded script (stored in repository):                            <<<<<<<<---------
    /path/to/script.sh script-param1 script-param2
  Mode:                         essential
  Timeout:                           1m0s

IMO it's a bug.
