Why i can stablish the ACTION AREA of an NPC?

When i put an non playable character in the game, the action are sems to be wrong. Why i can stablish the action area to that NPC? Like an object.
Thanks!

Now i working on a tutorial for visionaire in Spanish.

Don't really understand what you mean. What is excactly going wrong?
Maybe you have an invisible unnamed object in front of the npc which blocks it?

Novel now works fine. The png of the character is what defines his area?

Try it out.
However, it will be strange for the player if the name is already shown before the pointer hits the actual character.
