Might be the profanity filter. This game does weird things with it. Innocuous words and sentences get caught in it simply because a filtered word might appear in it. Try turning on the chat filter and typing in chat: “The grocery store isn’t open is it?” and see which letters the game censors. My guess is “grape” is being censored for the same reason. Maybe you can compromise by choosing an equivalent for “grape” in a different language?
