Lenovo ThinkPad X380 Yoga - ThinkPad USB-C Dock40A9 Display Issue

I hope someone can help me.  I am having an issue with connecting my Lenovo ThinkPad X380 Yoga to a USB-C Dock.  I have installed all of the drivers and enabled Thunderbold 3 within BIOS, however only the USB, LAN connections work when I plug the dock into the Laptop.  The two displays that are plugged into the dock via Display Port do not work and the laptop seems not able to detect the displays. 


Things I have tried:


Plugged in only one monitor using both VGA and DP but still nothing.

Uninstalled and reinstralled the drivers.

Ran the Lenovo support tool to make sure all drivers on the laptop are up to date.

Power cycled both the laptop and dock.


As I said the USB devices plugged into the dock seem to work fine as does the LAN.  I have tried to update the firmware on the dock however I keep getting the following message:


ThinkPad USB-C DP Hub version can't be checked!
Please power cycle the Dock to try again.


I have powercycled but still have the same message.  I am all out of ideas as to why the displays do not work.  


Any ideas?
