The Thomas Watson Collection was released in 2016. I am surprised that this typo remains for such a major work of his.
It was published in 1855, and those older works are often OCR'ed and not given much love afterwards, unless a user has reported the typo, and even then, I believe Logos does batches of typo fixes whenever they cycle around to update a particular book. With thousands of books in their catalog, there's a good likelihood of something older like this getting overlooked for several years, especially if no user noticed it or bothered to report it yet.
I hope you reported it using the Report Typo command. This "General" forum isn't really a place to report problems in books or the software. Another place to report problems in books is the Logos Resource Updates board on the Feedback boards.
Thanks Rosie. I reported it earlier today using the Report Typo Command. I posted it here as well to get a little more attention.
