Windows Desktop Client - Folders missing green checkmarks

Hello all, running OC 8.2, DT clients 2.2.4 and 2.3.1 After a reboot some users no longer have the green checks on sync'd folders in the file explorer windows. We still have full functionality of folders and files, just no green checks. Any suggestions on how to T-shoot this?

If its reproducable easily, please file an issue in github under /client with steps how to do it. It might be that your users have other file sync services installed which conflict?!

Thanks. There is not a sync client issue going on with other clients as some are affected by it and have no other sync clients running. Any other ideas?
