Default MacBook Air external displays are mirroring

Hi, I am using a MacBook Air (2019, Catalina) with a StarTech dock, DisplayLink 5.2.1, and two BenQ GL2460 monitors. However, the two external monitors act as a mirror of each other instead of two separate displays. I've followed the steps listed here https://support.displaylink.com/know...k-display-on-m , but it has not solved my issues. Any guidance on how to proceed would be great!

Thank you!

Hello,

Please verify in System Preferences, click Displays. Click the Arrangement tab.
Make sure that the Mirror Displays checkbox isnít selected.

Thank you,
Katarzyna

Hi, I tried that and it is not checked. I think if might be a problem with the dock I am using as the triple screen works on a different one in the office.
