MacOS - Overlay Icons missing

Dear community,

I have the latest OwnCloud build (Version 2.3.2) installed on my Mac using macOS 10.12.5.
The owncloud extension is enabled in the system preferences and I rebooted the system.

However I can´t see any overlay icons in finder (green arrows that do work for OneDrive and Dropbox).
Any suggestions how to solve this issue?

Thank you in advance and kind regards

Is your sync paused?
Can you run console (OS X standard app) and see if you get any error messages there?
