D6000 docking station, problem with HP laptop

Hello,

I have a dell D6000 docking station connected to an HP ProBook via USB Type-C. All devices connected to the D6000 docking station (mouse, keyboard, headset, charger) are working perfectly. The problem is that internet cable and monitor are not working? Somehow the D6000 docking station is unable to link them to my HP ProBook.
