It seems it uses the wrong key-name: journaltitle instead of journal.

If you make an item in BibDesk, it uses "journal" as the key.
If you want journal rather than journaltitle, use the Better BibTeX translator rather than the Better BibLaTeX. Journaltitle is BibLaTeX-specific; BibDesk probably wants BibTeX
Thanks, it works perfectly now. I've been seeing ghosts, I think I should call it a day :) may this be closed now?
Sure; I just don't like to close an issue until I'm sure the customer is satisfied :)
