UD-ULTCDL Windows 10 USB C Connection Issues

Hi, I am having an issue with my USB C connection seeing all the monitors I have hooked up. Currently I have three external monitors connected to the USB-C plugable dock and only on that is hooked up via a USB port is working. The HDMI and DMI connected monitors are not working and have ran various tests and updated all softwares for Win 10 and for the docking station. It appears to be hardware related as I have unplugged each device while watching the USB connections within Device Manager and it stall will continues to show an error connecting up to the docking station. I am going to try another cable from my laptop to the dock to ensure it’s not a cable issue. If not, that leaves only the dock remaining. Any advice on any other troubleshooting left I could do before I buy another dock?
