Kami Uploads folder since October 2017 - What gives?

Hi. In October 2017, Kami started to store files in a folder called Kami Uploads in My Drive on Google Drive. Also, now when I open a file in Kami that I have worked on previously, I am asked to select a version or create a new one. Before October, the auto save feature seemed to work seamlessly with Drive. It automatically updated it and that was that. What’s going on? Can I fix this? Can I delete files in the Kami Uploads folder?
