FCPX music trimming snafu

Brand new to FCPX, but a veteran to the original, and fresh off a 40 video series from Steve Martin of Ripple Training, so I feel pretty comfortable. However, can't seem to figure this one out.

I start out a storyline with 5 songs of audio. Then I slice sections and remove the middles. Next step is to fine tune trim the edit points, however, when I add head frames back to the A side of the edit, those frames are muted and the waveform for those frames is closed in with a blue rectangular box. Likewise, when I trim out the tail frames of the A side, the clip moves, but I can still sort of see the waveform beneath the B side, as though it is behind it. The result is that the audio from A and B are still overlapping and playing together, even though I trimmed them out. What's going on here?

Hmm. I tried to follow the embedded image tutorial on CC correctly. Let me try again.



Ah, there it is.

So, I can't seem to get this to happen again. I started with a fresh storyline, and tried to do the same steps, but I never again saw this blue are of muted music. Everything worked fine. But should I stumble across this again, I'd sure like to know what it is.

Well, it would be just like me to run into a bug on a maiden voyage for software, one that makes me feel like I don't know what I'm doing. :)
