Hello, 

If you’ve created a gradient, shape, and text on the V2 track but they’re not appearing in the Program Monitor during playback, it could be related to track visibility, layer settings, or an effect.

Could you share a screenshot of your timeline and Program Monitor so I can take a closer look?
