[problem with m3u playlist]

Hello,

First scuse me for my bad engligh, i am french.

I have a problem with m3u playlists. I use Poweramp on android to manage my playlists. My playlists are located on the root of my sd card on the phone. 

Each entry of the playlist is like this : 

#EXT-X-RATING:0
name folder/artist - title.mp3

 

When i updated my playlists in the powermap app in the past, the entrys was saved to the m3u playlists, so i was able to use these playlists in my computer (my music folder is synchronised with dropbox in my sd card and my computer).

 

But recently i updated my playlists on my phone, the titles appears in my phone, but not in the m3u playlist, so when i transfer my m3u playlists to my computer, new entrys don't appears (i opened it as .txt file in notepad to check it)

 

I don't know how what appened? Maybe an update of the app, or a bug ?

Thanks for your answer, it's very important to me, because i use m3u playlist for my job.
