USBC-MSTH3 Screens Will Not Display

Hi, I have a brand new setup that I was super stoked to have. I’m running three Samsung S3 Essential 27-inch Monitors off of my HP Omen 17-ck1xxx. This is powered by the USBC-MSTH3. I can get it to work, and when it does, it is fantastic. The issue is that I cannot reliably get it to work. Whenever I take my laptop off the dock and plug it back in, it is a huge battle to get the setup to fire back up again. The screens just stay black with their lights blinking, and the computer does not recognize the screens. It takes me like 20 minutes of turning stuff on and off and unplugging things before it will just randomly start working. Please help me figure out how to just get this to work, or what sequence I need to do things in, in order for it to run properly after being disconnected, because this is a disappointing nightmare.
