Music player creating duplicate folders

[AC Question]

On my htc dna after multiple updates I cannot add music to a folder. It will show the music in the folder on my pc or in a file explorer but in the music player any music I add goes into a new folder with the same name. For example, I have a dubstep folder with hundreds of songs but now if I add a song to that folder it will make a new dubstep folder with just that song or any I add after that. I don't know when it started doing this but I can't seem to fix it. I don't understand why it would do this.
