NPC Chat Command

Hello!

I am trying to create an activity for students to create NPCs with command buttons that will lead the NPC to speak in the Chat box. I'm coming across 2 issues:

1. The first NPC created (let's call her Sally) says: Hello!. The player will have 2 options: Command 1 Button will say "How are you?" and Command 2 Button will say "What's your favourite colour?" The buttons work, but when Sally responds, the chat says [NPC] "I'm fine", and doesn't say [Sally] "I'm fine."

2. If I create a 2nd NPC beside Sally, named Jenny, her Command buttons do not work. I was trying to get Jenny to also respond to questions, but when the buttons are pressed, no chat comes up.

If anyone has encountered either of these issues, please let me know! Thanks so much!
