The program doesn't fully transfer playlists for me

[nokeeb]

I used this app for more than a year now and I was always very satisfied at how stable quick and simple it is.However, i've noticed a bug using it today that some playlists i try to transfer wont fully transfer, it transfers the playlist itself (the name of it) and only like half of the songs.I transfered 2 playlists, one 53 songs successfully, but the other one i mostly use only transfer 96 out of 195 songs.And it transfers the same 96 songs everytime.
