Changes made to projects and folders did not save from last work session.

Hello! I had shared a project with a co-worker, but instead of sharing just the one project, all of my projects in that particular folder were shared with my co-worker. I went into each project and removed her name from the 56 projects that she didn't need access to and then created folders for each of my co-workers. I then moved the projects that each needed and shared the projects with them. I created seven folders and moved the 57 reports into the correct person's folder. Today, when I opened Adobe Analytics and went to that folder,  the seven "sub" folders I had created were there, but the reports that I had moved were not. Also, all of the reports I had "unshared" with my co-worker had her listed as sharing again!  Anyone out there that can give me insight on what I did wrong? I don't want to "fix" this again, to only have it happen tomorrow when I open Adobe Analytics. Thank you in advance.
