Opacity in background image after using Quick Mask mode [edited to include link to image]

Below is an initial post I made to the mailing list. I was asked to include a link to the image I had originally attached, as the list drops attachments. Thanks for any help.

Hello,

I am attempting to remove the backgrounds of some scanned grayscale jpg images, using the free select tool to rough outline the selection, and adjusting the selection for fine details using the quick mask mode (see attached screenshot). This requires switching to RGB mode. After refining the selection, I switch off Quick Mask mode, invert the selection, and then clear the background. After clearing, I end up with patches of opaque color where I drew over the image to alter the selection. Not sure what I could be doing wrong. Can someone please help me with this?
