I don’t use Cockpit/Houston, but there have been a few posts here like the following suggesting switching between the cockpit-zfs and cockpit-zfs-manager modules due to some sort of bug, or perhaps those bugs are resolved and you can upgrade cockpit-zfs.
Perhaps @Braeden-45Drives can reply with how you should proceed.
