Macbook Pro and Triple Display Docking

So I want to drive two external monitors with the Macbook Pro closed. Running High Sierra 10.13.

So far I can not get my Triple Display Docking station to run more than one external.

I can get both externals running if I plug one monitor directly into the mac, and the dock into another plug.

How do I troubleshoot this?

Thank Mac, that did work, sort of. I was not getting the blocking message. So I uninstalled the displaylink, then reinstalled, and got the message, allowed it, and it is now working. Thanks!!!
