I started searching for righteousness and noticed a bunch of weird terms in the auto-complete dropdown menu, after the expected ones (note this list I've already scrolled past the first three which I deemed OK; righteousnesse is likely an older English spelling):

I'm going through looking at these to see where they come from. Some are typos (which I'm reporting as such), but two of these (Righteousnessa and Righteousnessb) come from these occurrences:


The footnote reference markers are included with the word in the index. That is erroneous. It also means I could not find these occurrences if I were looking for just righteousness.
