Razer Blade 14 + TB3 docking station + dual monitor

Hi there, I tried a Razer Blade 14 (i7 7700HQ + GTX1060) for to use within a dual monitor setup. First i used a Lenovo ThinkPad Thunderbolt 3 Dock Gen 2 - 2 monitors at same time with 4k/60Hz are working fine. When using a CalDigit TS3 plus docking station, only 1 monitor at a time is working. Anyone else here is using a CalDigit TS3 plus and got it to work with dual monitor? Any help onhow to get this setup working is welcome. Best regards, cairon
