More information on this.
The different looking feeds I believe are from when I created the manual feeds (in 7.2.2) and now. The down side is that it appears the feeds were not updating themselves. Perhaps it takes a new post to update the cached feed.
It also appears that the reason that the feeds are "always active" is because if the checkbox is unchecked it passes no value and the form page isn't smart enough to see an unchecked checkbox.
