Question Weird Bug with Dialog System

I am experiencing a strange bug with my dialog system. The first two lines of dialog are duplicated and the characters name is not shown.

This is the first line presented to the player as soon at they approach the NPC.


When the player presses left click to advance to the next line, it only adds a space to the existing line going from "Greetings!" to " Greetings!".

Upon clicking again (at this point 3 lines in), it correctly displays the second line of text. This is the correct format for the text. All other lines after this point are correct, which continues until the end of the file is read.


Any help at all is appreciated.


Here is the code for the character, and the dialog system:
