MP3 Trimmer Error

[Ktk]

I have this song. I'd like to trim it. In fact, I have it trimmed on my phone right now. It plays perfectly with no problems. However, when I save it to a folder (Tried different names and deleting all the saved files of this trim) and play it, it plays a different part of the song.

What gives? =[

edit: Just tried a soft reset. Still doesn't work.

edit2: Tried trimming a different part. I get the same part as the trim before.. =/
