Linking requirements to Design Management

Hi!

I tried to create link between Doors requirements and model elements in Design Manager (ALM Jazz Team Server). From the Design Manager I can create link to Doors using Doors Web Access, but the created link does not appear in Doors, just in the Design Manager. From Doors I can not create link to the DM because if I start the predefined link I see nothing about the DM project (see the picture).

Questions:

Why can not reach the Design Management project from Doors? 

If I create link in Design Manager to Doors than this link why not appear in Doors database?

Thanks for your help!!
