VM snapshort Date/Status delete

I have a snapshot which I stopped from completing (cancelling via GUI). However, the snapshot is still visible with a status of delete
Attempt to remove it gives an error

lvremove snapshot 'pve/snap_vm-105-disk-1_gas' error: Failed to find logical volume "pve/snap_vm-105-disk-1_gas"

I then have to unlock the VM

How can I safely remove the snapshot
