Problem importing requirements via ReqIF

Hello, I want to import requirements contained in a file ReqIF however once imported the identifiers do not appear :
The information of identifiers being I think stored in Req IF ForeignID because when I delete the requirements file can observe the associated identifiers (REQ_01, …) in the dialog box.
How to handle this problem ?
Thank you in advance.

Did you checked the “Preferences” section in Requirements Viewpoint Help ?
Maybe by changing the import preferences you can at least debug this issue.
Hope it helps.
