Camera position Tween stopping and suddenly snapping camera to final position

Question

The camera in my level scene is set to follow the players position.y except for when the player enters certain areas, in which case the camera position is tweened between the player and a given point (a marker2d). This tween works fine, however the tween I am using to reset the camera’s position back to the player, the camera barely moves for the entire duration of the tween, and then suddenly snaps to the player’s position. I have include my code for the camera, and I would include some gameplay to showcase the issue but I am unable to because I am a new user. I am not sure what is causing this, some help would be much appreciated!

CODE 1:
