Halion Sonic Panning Issues

So I’ve tried multiple different instruments inside of Halion Sonic but it seems to be that certain instruments are panning all the way right automatically and every time I manually fix the pan towards Center it only last for a minute or two then as I’m working on the beat the instrument will pan all the way right again on it’s own. The only work around I’ve found is to render the track in place to get the wave file once I’ve turned the pan back to center. My question is why is it doing this and how can I fix this? I have a lot of awesome instruments in Halion but it seems counter intuitive for production when a bug like this exists. Let me know if somebody has been having a similar issue.
