OneDrive File and Folder Status Icons (Solid Green - White Check) Not Showing After Reboot

Today I uninstalled the trial version of McAfee, checked that Defender is up and running, then restarted. All is well, except the status icons (solid green disc with white check) are not showing on folders, subfolders and files that I've placed in OneDrive to sync and backup. Hovering mouse over icon on right side of taskbar shows "Up to date". But why have the status icons for the folder and files disappeared and how do I get them back? Thanks.

Solved. For some reason, after restarting, the "Status" column was not showing up on the folder view. I "ticked the box" and it appeared, but still no status icons. I then restarted Windows Explorer and that did the trick.
