Folder available in web interface but not in desktop client

Nextcloud version:
Operating system and version: Ubuntu 16.04
Apache or nginx version: Apache/2.4.18
PHP version: 7.0.28

When I login with my user (or any user, admin included) to the Nextcloud web interface I have a folder which is shared with me. Inside this folder there are 9 subfolders, all accessible, visible, and downloadable to me. But when I connect to Nextcloud with the same user(s) using the desktop client I can only see 8 subfolders in this one folder. I’ve tried:

occ files:scan --all

To try to get the server to find this last folder with no changes. What has happen to this last folder? To summarize, I can see a folder through the web interface, but not when I connect with the desktop client.

Is this the first time you’ve seen this error? Yes
