ZFS Snapshot taken, but GUI does not show Snapshot

[git192prox]

After taken a ZFS Snapshot with the GUI (Proxmox 6.2-11), the GUI is writing, that the Snapshot was taken successfully.
After clicking again to the GUI Snapshot context, the snapshot is not visible.

But on CLI by entering "zfs list -t snapshot" the Snapshot for all the attached Disks into the VM are properly showed.

Do you have multiple disks by any chance?

 

[git192prox]

i'v attached three ZFS(zvol) Disks to the VM (two of them over virtio, one of them over scsi)

Sorry I just realized that the answer to my follow up question was already provided. I think someone from the Proxmox team needs to have a look onto this...

/edit: what's the reason in using different disk types? Have you tried to consolidate to SCSI or virtio?
