USB-C Triple Display Docking Station Not Working

Just purchased a USB-C Triple Display Docking Station and it doesn’t seem to be working. I have all the cables plugged in, and the blue light is on. When I go to plug the cable in from the host port to my 12" Macbook, nothing happens. It doesn’t recognize my display and it’s not delivering power to charge my laptop. If I run my laptop charger from the outlet to the host port, then a USB 3.0 cable from the front port on the docking station to my laptop, it charges, but still won’t pick up the additional displays.
