Anyone have any idea how to fix this?

Here is the dock:

My MacBook pro is the 2016 13" with 4 thunderbolt 3 ports.

For your reference, DisplayLink technology is a combination of hardware and software.

According to the information provided by HP for your HP docking station --> https://support.hp.com/us-en/product...17?sku=50H55AA the docking station you are using does NOT have DisplayLink hardware inside of it.

As a result, DisplayLink will not be able to assist you.

Your description of the behavior suggests that the HP dock has a DisplayPort Multi-Stream Transport (aka DP MST) hub inside of the unit. Macs do NOT support DP MST, which is why your displays are mirrored.
