Proxmox 8 / ZFS 2.2 Bug?

[Mrt12]

Good day,
I have recently installed the latest updates on my Proxmox 8 Server which updated ZFS to version 2.2 as follows

zfs-2.2.0-pve3
zfs-kmod-2.1.13-pve1

and now, when I run either one of arc_summary or arcstat, I get loads of errors, as shown below. I believe this is a bug, but I am not sure how to fix, as I believe arc_summary and arcstat are parts of ZFS, but on the other hand, I think the ZFS update came through the Proxmox update. Also I am unsure how to fix. Any hints?
