Incorrect emlem/icon for Nautilus

After syncing my Google drive, I have a directory/folder that won’t update the emblem/icon to the Green synced tick.
I have tried adding a new file from this and another computer and the synching works but the blue icon remains.

How do I reset this - its more of an annoyance than a big issue.

Apologies I should have added this is Ubuntu 16.04 and version 1.3.22.
Also note my other machine is showing all icons correctly.

Users should be prompted by Insync to automatically install available plugins. If that doesn’t work (or if they’ve rejected the plugin install before), they can install insync-nautilus using their package manager (i.e., apt-get or yum).

I have installed the plugin correctly. All other folder are showing the correct Green icon.
There is one folder which although fully synched is showing the blue icon.

I have tried adding and removing files on this directory, but the icon doesn’t update.

I hope that is clearer.

I managed to get this to reset after a couple of rounds of deleting the folder and recreating it.
