Some of the tokens used in the MonthHeader options of the current DiaryGridLine refer to X different languages, although the number of languages selected in the languages property is Y, a smaller number.
You will not be able to generate this diary until this error is fixed.
Solution:
•Edit List of Languages: Opens the Languages property editor, so you can add or remove languages.
•Modify [MonthHeader]: Opens the corresponding MonthHeader options (located in the GridOptions), so you can modify any token errors.
