Minor VM Migration Issues (PDM Beta)

PDM 0.9.0 Beta
Proxmox VE 8.4.12 (origin and destination)

During migration of a VM from a cluster to a node I noticed two relatively small issues

1. Migration progress prints constantly to the same line. Line width continuously increases instead of printing to a new line (intra-cluster VM transfer behavior), which makes it difficult to check the status of a transfer.
2. Migration from cluster to a non-clustered node with Delete Source unchecked leaves the original VM in a locked migration state after transfer is complete (can manually remove the migration lock from /etc/pve/qemu-server/<VM_ID>.conf).

I am having the same issue with progress printing in the GUI.

I also am experiencing slow migrations between a Proxmox 9 standalone host and Proxmox 8 clustered host. ~14MB/s on a 10Gb link.
 
Came here to post about his. Not much more than a minor annoyance but I have now had 3 VMs left with a lock on them after migration between nodes in PDM.

My difference is that I have no cluster on either node. I am testing this in my lab as an alternative to clustering and have set up 2 new hosts with PVE 8.4-1, set up PDM on a VM on one host, added both hosts as remotes, set up a VM to migrate, and started the process. It was fairly quick to move a 50GB VM but all 3 times, the source VM gets left with a lock on it.
