That's not the issue. They're asking why the word "bell" is on there, not the person's name. The person's name makes perfect sense, at least to us English speakers. The "bell" part doesn't; it would be look your expensive utensils each having inscribed on them, "Ravi's fork" or "Ravi's spoon". You can look at it and tell it's a fork or spoon, so why would you write that piece of obvious information on there?
