Playlist track mystery

Hello forum goers,

I am trying to make a playlist but have stumbled across a perplexing bug. As far as I can tell my playlist is formatted property and all the files are where they should be, but when I play the playlist almost all of the songs are overridden by one song. Instead of track 1 > 2 > 3… >10, it goes 1 > 2 > 2> 2… > 5 > 2 > 2 > 5

Any ideas?
Best,

What method (software) are you using to create your playlist? Maybe post a short example in a reply message? Are you using a Windows or Mac computer? Mac computers create an end-of-line character not recognized by SanDisk players. ALSO, make sure the internal shuffle
command is not active.
