Here's a sample of the spell check results on an eBook. This is just a sample, as this happens with all books.

Note that words that are obviously spelled correctly ("as", "at", "be", "bed", etc.) are listed, even though "Show only misspelled words" is checked.

In addition, those words appear much more often than the listed count, but it looks like the spell checker thinks that only one instance of the word is misspelled.

The eBook has the language set to "en" (no qualifiers like "en-US") in both the OPF and each HTML page. In "Manage Dictionaries", "United States" is set as the preferred variant for the English language.

Is there any other config I should look for that might be the culprit?
