Fromfilename found nothing

Hi there,
I’m new to beets so I hope to get some help here. :wink:
I’ve installed beets under Manjaro and it’s working so far.
I’ve added the fromfilename plugin to yaml and beet version shows that it active.
So I hope it’s active.
I tested it with single mp3 tracks (no album) with no tags (deleted all tags before):
ABBA - Fernando.mp3

So i typed: sudo beet import -s /mnt/Audio\ Central/Tracks
Result: No matching recordings found.
If I type E for enter search and type the artist and title everything was found.
But what do I wrong if no title is found by default?

Best Udo
