import tracks bug on airtime 2.2.1;

Hello to all from greece.
I upgraded before 3 days from 2.2.0 to 2.2.1 and i have this problem.
Then i import tracks from the web interface to the library the paths of the tracks in the imported directory are wrong.
For example.

I add these tracks with name trackone.mp3 . The mp3 tags are
artist: boo
album: foo
tracknumber: 01
kbps: 128

The album has 10 tracks but i add only the first.
Before the update the track saved in imported directory as
/boo/foo/01_trackone_128kbps.mp3

after the update the track is saved as
/boo/foo/01/10-trackone-128kbps.mp3
and if i add and the second track of the same album the path is
/boo/foo/02/10-tracktwo-128kbps.mp3

All the tracks have the number of tracks of the album in the start of their name and their track number is an extra directory in the album folder.
I tested with different tracks an albums but it is always the same.
Does anybody else have the same problem; It is a bug;

Thank very much and sorry for my bad english
