My clientlist_b_xx files get deleted and all Incremental get deleted back to last full

Hi,

Please help. I have one client that this happens with every night. Backup goes through and then later, I think it is when
clean up runs. It deletes clientlist_b_X files off server and then removes all Incremental backups so I am only left with a full backup which in 2 weeks old. I then end up restoring all form a Windows backup I am running of Urbackup server.

Errors below. Please advise what additional info you need.
