Fix dictionary translating from US to UK (and vice versa) in macOS High Sierra
Dictionary not working correctly after upgrading to macOS High Sierra. I translate many documents from US to UK spelling (and the reverse). The dictionary used to work perfectly, but since moving to High Sierra neither dictionary recognises incorrect spellings from the wrong continent. It thinks all the spellings are correct. I've checked all paragraph styles, basic paragraph styles and preferences to no avail, so deleted my preferences but this feature no longer works.
