How to select entire blob with Shift + CMD

Hi Guys. I’m using Shift + Command in the Project view to adjust the gain levels of my waveform “blobs” in an audio track. Why does Cubase often only grab part of the blob like this?

I thought it would do a better job of detecting the entire blob. I tried turning of snap, but it didn’t change anything.

Thank you!
