Cant see available tracks for adding a SC

Dear all,

I would like to add another SC (KMC-BC) to one of the tracks of our customer. To be able to do that I navigated to CMS of the NWDI, but unfortunately Im not able to see any of 3 tracks configured by the customer and usable through NWDS.

To able to add an component to a track, I need to jump to the Transport Studio, marked on the screenshot. This is probably not possible, if no of the configured tracks are visible. Am I doing anything wrong? Thanks you in advance,

cheers
