Default Pop OS 20.10: Docks working only through HDMI not Displayports

Hello there,

I am able to install the displaylink driver quite fine, however the Monitors connected on Displayports refuse to work.
I can't exactly tell since when these issues occurred as I weren't using my dock for quite a while now...
I could use these connections fine around kernels 5.5 - 5.7 for sure.

I did a clean install of Pop OS 20.10. to stay clear of any side effects.

Code:

0 is the builtin monitor of my device.
1 Is the monitor I connected with HDMI to my USB-C Docking.

I am using This Dock from i-tec or This Lenovo USB-C Dock .

I've never experienced any trouble with these dockings before.
