Dell WD19S Dual Monitor show as one output

Hi,

I have a WD19S docking station with a Precision 7510 laptop and two external monitors. Both external monitors are connected via DisplayPort to the docking station. However, both external monitors only show up as one device and the content is mirrored. I already upgraded the docking station's firmware to the newest version. I'm using i3 as a window manager and Xorg as display server. In addition, I installed xf86-video-amdgpu and mesa.

How can I use both external monitors as separate ones? Thanks for your help! If you need further output, I'll provide it asap.
