Why I Can Only Choose "Clean Restore" As Restore Method?


I have a plan of incremental backups and when tried to restore current “Snapshot 5” I was offered only “Clean Restore”:


I didn’t even have option of choosing where to restore to so I assume what it would do is restore entire partition overwriting everything? I just want to restore files from “Snapshot 5” but I don’t want to have everything restored which would mess up the system.
