Syncing audio in Final Cut Pro X doesn't create a compound clip

I just had a quick question that hopefully someone can help me with. I was shooting some video with my Canon t3i the other day, and I record audio into a Zoom H1. I imported all of my audio and video into Final Cut Pro X and I wanted to syncronize the clips, so I chose the video and the correct audio to go with it, and I right clicked them, and chose syncronize clips.

Now, my question. On every example I've seen of this, syncronizing two clips creates a compound clip which would be great, but when I choose syncronize clip, it just creates a new clip of the video with both audio files apart of the video. It's not a compound clip at all, it's just a video file with two audio channels, one with the cameras audio, the other with the Zoom H1 audio. When I go to shut off the cameras audio channel and just leave the Zoom H1 audio, my video starts to skip and just goes black, yet the audio plays fine...

I guess I'm just looking for help, is there something wrong that I am doing when I am trying to sync these clips? Are there certain file settings that I should have? My video is recorded in 1080p with 24fps, the audio is recorded in WAV format. Any help would be greatly appreciated, thank you.
