Why are audio levels displayed different when working inside & outside Multicam?

I'm working on an exercise show, and I made a Multicam clip first. Inside of that, I was going to adjust the audio for the camera that's got my good audio. I added an EQ and a Compressor and got it where I wanted it. Then when I started editing inside the Project, I noticed that while my audio SOUNDED the same from my ears, it was reading different measurements on the EU meter.

Inside the Multicam clip, it peaks at just over -12. Outside the Multicam clip it peaks at just below -12. Here are images to see.

Please let me know why this is? Am I doing something wrong? Or is it a bug? Or is this something I'm just not aware of?

I consider it a bug. You often have to do minor tweaks once the multicam cilp is in a Timeline.

So what kind of tweaks do I need to do? Do I need to just make the audio a compound clip and then lift the audio again to get it up to zero?
