The "not selected" list doesn't refer to your current pages. It's the difference between everything they've ever crawled, since the dawn of time, and your currently indexed pages.

The Official Docs specifically say that "not selected" includes redirects. So if you're redirecting anything non-canonical to canonical-- which is exactly what you should be doing-- that would make the list shoot through the ceiling right there.

So the list will never get shorter. Just ignore it-- deselect, haha, the option of viewing it at all --and make sure your current pages are all in order.
