Cascade Particle Alpha over Life

Color over life will not change Alpha

I followed along a tutorial and made sure I put in everything correctly. No dice.

I want to spawn smoke particles with Zero alpha and slowly give them alpha until .7 and then back to zero. The effect SHOULD fade the alpha but it doesn’t.

I’m not sure why the smoke particles just pop in and out of existence. In the tutorial I followed they fade in and out at this point. What am I missing?
