Missing Folder Icons for all One Drive folders and sub folders

All the folder icons on my One Drive Main folder and all sub folders are missing (just blank). They show up under Windows Explorer. All other folder icons show normally.
I tried changing the icon and that did not work, i.e. no icon shows up.
Not the end of the world but I would like to get the missing folder icons back..
Thanks for your help.

This is due to a bug in OneDrive. We added a workaround which solved the issue in 11.18 but I don't think there's any solution for Opus 10 unfortunately.

Thanks for getting back to me so quickly.

Guess I will just have to upgrade
