Skyrim Special Edition Scene Troubles

[MackenzieBeyer]

Hi there, I've been struggling pretty bad with scene creation for Skyrim. I am trying to make a simple scene with dialogue between two npcs, with a couple packages running. However, no matter what I do or change, only the first phase plays out, after that, they stand there just awkwardly staring at each other. There was only one time the second NPC said her line in the second phase, but it seemed random as to why. This scene is within the parent quest. I have tried making a simple Actor Dialogue Event to see if that worked instead; ran into the same problem. I attached screenshots of the scene. I'm sure I'm doing something wrong, but for the life of me, I can't figure out what. Any help would be much appreciated.
