Most displays do not have support for such resolutions, so as a result the displays are most likely using the more common 1920x1080 resolution as a fallback.

To put that another way, it would appear the behavior you are seeing is an internal hardware limitation of the dock itself.

Hi thanks for your comment. Yeah I'd seen that, but it states the maximum resolution is 2048x1152 only when two HDMI outputs are connected. The way I've got it setup is 1 monitor is connected via Displayport and the other monitor is connected via HDMI.
