In the season 11 episode where Lucille had her miscarriage, the PBS subtitles had Phyllis telling her "I'll see to Mrs. Heslop and to Mister." in the BBC subtitles, "Mister' was changed to "Miss." Both made sense since Miss was obviously referring to their newborn daughter and "Mister" to Mister Heslop who was eager and well-meaning, but not always helpful.
