Fluid Breaks Merlin Clarinets

About a month ago when I would test out Merlin soundfonts, whether it was gold or silver, the sustain on the clarinets sounded normal. Now when I play any series of notes with clarinet, there's a small pitch bug accompanied by a buzz that unfortunately affects the quality and mood of the piece I'm playing.
I'd attach an mp3 to demonstrate the bug as best as possible, but I can't.
