How do I import Link To/Link From using ReqIF in RDNG 6.0.6 iFix 8?

I used ReqIF to create the export from Project area A. My export has 1 Module (containing 13 artifacts) and 1 additional artifact not in the module. I have established 3 links across the 14 artifacts. The report summary that generates after the ReqIF export runs shows me what I expect: Exported 1 Module, Exported 14 Artifacts, Exported 3 Links.
When I import the .reqifz file into the new project area everything imports correctly except the links. There are no links across the artifacts.
What steps am I missing?
Thanks!
