Rem's voicelines for "careful" only say the character name but not the callout?

Not sure why this would be intentional, but Rem does not audibly say "careful xxx", but instead just says their name and nothing else.

Had a Rem in my game keep pinging just "Ivy" it was funny lol, then I played a game as him and realized it was an issue with seemingly every careful he tries to ping??
