ThinkPad X1 Carbon 5th gen can't connect 2 external monitors in X1 Carbon Thunderbolt 3 Dock

Hi!

I just got a new "X1 Carbon 5th Gen - Kabylake (Type 20HR, 20HQ)" and a "X1 Carbon Thunderbolt 3 Dock". 
I have an external screen connected to the dock and it works fine (VGA connection). 
I also have an other monitor with display (DP) connection that I want to use. 

But my computer can't find the other monitor, only the one with VGA connection. 

Is there any easy ways to fix this problem?

Best regards

I assume you have independently tried the DP monitor by itself?   I'm running 2 DP connections on my x1c5 and it works fine originally in 2 DP connections and now in in 1 DP connection + daisy chain from the first monitor.

Yes, i tried it in an other computer and works fine. It also works fine if I dont use the Thunderbolt 3 Dock, and just connect it straight to the PC. But when both monitors are connected to the dock, only one works. The computer can't even "find" the other screen.
