Requirements implementation doesn't show up

[Gabor]

Hi,

If I choose the "Project/Documentation/Implementation Details..." on my functional requirements folder, the table doesn't show the unimplemented requirements, only the implemented ones.
The same dialog shows UseCases well.
Is it any knowed issue, or is it Me, who do something wrong?
Thanks in advance.

I'm erroneously set UseCase as target instead of Requirement on
the Requirement package. I thought, that requirements implemented by
UseCases, so the Use Case is the valid target
