I'm checking the regular and ?useskin=Mercury versions against each other, and I see some missing too (next time, include which lines are missing!).

The only reason I can think of is that Mercury omits section headers if the section is empty. As it collapses sections automatically, having an empty section creates issues. These are all third level headers, so they're all counted as separate sections, even if you didn't intend them that way.

If that's the case (and it is still a guess) then you can't fix it. Instead, you have to fix the page. There's no reason to use that many headers, that's just not what headers are for. I It's better to make a bullet list with indents instead.
