Cinema 4d dynamic tutorial - The Creation

Hi there! Super tutorial but still have a problem at the same point,
First of all, in my Motion Drop, I only have the collider body activated, and not the other one I can see on your screen..? What is the name of it? Did I miss something?

Then, when I activate Enable Dynamics just after done the compositing tag,
my Motion Drop goes crazy and doesn't go where my path is supposed to be going.

Thank you in advance for your answer,

Keep doing it :)
Cheers
