Issue with importing Track Archive in Cubase8

When importing track archive from Project A into Project B, Project A’s tracks will appear but with no track information. no midi, no audio, no nuthin… If I try to import Project A archive into Project A itself, it works fine. Tracks and track info import properly. Can any of you wise gentleman help me?

I’m using Cubase 8.0.20 on a PC running Windows 7
