Glass Harmonica all different on MU4

I composed a score with glass harmonica in it on MU3, and it sounded great. But when I imported the score to MU4, the soundfont sounds almost the same, but with a ton of whining synth string sounds layered on top. It's the same with "Bowed glass" or "Musical glasses". I tried to upload the scores' audio, but the forum doesn't take audio files like mp3. How do I get this awful synth sound to go away? Any help would be appreciated. Thank you!
