Clamshell Mode Not Working

Setup:

MacBook Pro 13" (Mid-2012), Latest Mac OS Catalina 10.15.6
StarTech USB3DOCKH2DP Dock, connected via USB 3.0 to Macbook (latest firmware)
2x ViewSonic VX2452 Monitors, both connected to StarTech Dock via DisplayPort
Latest DisplayLink App installed

Issue:
The external monitors black out every few minutes for a couple seconds whenever I close my Laptop screen. Energy Saver settings are set to never allow the computer or monitor to sleep. I am having zero issues when my laptop screen is open. I have the DisplayLink Manager App installed (Version 1.0.0 Build 54.71)
