BTW, this might not be the proper place to post this, but since the link of the song is here, I'd rather ask the question here also.

I was just wondering why in the 4th bar, the drum style changed even if I haven't indicated any change in substyle. Is this a bug? This happens occasionally in some songs I'm working on. But when I change to another song style, the problem disappears. Have I done something wrong in the settings?

Thanks.
