blank refrence field of imported articles

Hello!

I recently have the problem that of some articles the reference information is missing. Now if I quote them, only the pdf name appears in the reference section.

Is there anything I can do about it or any specific reason why some pdfs are not obtaining reference information? Or should I simply enter reference information manually?

Thanks a lot for any ideas!

Cheers

C.B.
