Why does my dialogue disappear after a certain bock?

The dialogue in my game has really been messing with me, I just can’t seem to get it right! My second dialogue only seems to appear after a certain block. The starting frame of the level before the player and camera start to move seems to be the only space where my dialogue can work properly. When I position it past this point, it doesn’t appear at all- even if it was working in the UI test. When I put half of the words past it’s limit, it just follows the camera on the edge on the screen with only the half in the working area visible. Is this a normal game thing I didn’t know about? Any help appreciated! Game link: Flowlab Game Creator - Math Quest
