LMS 7.9: bug with m3u and cue files

Hi!
I think there is a bug in LMS 7.9 (using Daphile that is LMS based).

First: to add some music to my playlist I use always folder browsing (I don't need the database).

I have several albums stored in flac files (one file each song). All song for an album are in a folder.
If in the same folder with the flac files there is also a .cue file and/or a .m3u file, when I try to play all the tracks in the album adding all songs to the playlist, the first track is always skipped: it seems that LMS can not recognize this song as a music file (but a generic binary file).
Deleting cue/m3u files not always helps, and not rescanning library for new or changed files.
But if I copy all flac files in RAM Drive (or in a new folder), the first track is played normally.

There is also a bug cue related.
In a folder I have two cds ripped in a single flac file + cue sheet, as follow:

album1.cue
album1.flac
album2.cue
album2.flac

I can add the first album to the playlist clicking on the album1.cue, but also here the first track is skipped.
Sometimes the track in the album is added two times in the playlist.

I hope that this can be solved.
Thanks for attention!
