The template name '"Moderate" business letter' is weird and looks like a typo compared with '"Modern business letter'. Both names lack on the information serif/sans-serif. And in bug 107513 comment 2 it was suggested to remove the quotes. So I propose to rename the templates to 'Modern business letter sans-serif' and 'Modern business letter serif'.
