What is the source of this numbering anomaly in Ambrose's De Officiis?

In at least two editions of Ambrose's *De Officiis* (*On the Duties of the Clergy*) there is a numbering anomaly in Book 1, Chapter 38, where paragraph numbers 190-199 are skipped, and paragraph number 200 is used twice. This can be seen in [CCEL's online edition](http://www.ccel.org/ccel/schaff/npnf210.iv.i.ii.xxxviii.html) . It is also present in [a paper edition](http://www.amazon.com/On-Duties-Clergy-St-Ambrose/dp/1849026165) which uses the same translation. What is the source of this numbering anomaly? Do other translations or editions have it, or is it particular to the Schaff/De Romestin translation? Or is it limited to the CCEL edition? (The Benediction Classics printed edition I saw made no mention of the CCEL, but I guess it's possible they simply copied and published the text of the CCEL edition. Seeing as it's out of copyright I'm not sure if that would be illegal or not...)
