Fire in blender

DarkFire002

I'm creating an animation in blender and in my scene I want braziers that light up in sequence, I followed this tutorial on YouTube to create the fire but I have a problem. Since the flame must start after 200 frames I changed this parameter, the problem is that all the time the flame is not lit in its place there is a cube of smoke. Anyone know how to fix it?

this is the tutorial I followed -> https://youtu.be/LYy_YaoMTck?si=Edqi9veHG3Dp7go9
