You have unused disk that are related to an existing VM with VMID 114. To be able to delete them, you need to tell Proxmox to relate the disks to the VM and them remove them from the VM config.
On node h63, use qm scan --vmid 114
. It should find the orphan drives and link them to the VM configuration. If not, issue the command a second time. They will show up in the GUI as unused disk in the VM and you'll be able to remove them from there.
