Colliders Morph Object, change in-Game

I got a morph target who scales with a timeline to get an effect.

This is the first state of my morph target.

And this the final State.

I don’t know why the collider got the first form, and don’t want to change. Is that possible? change collider in real-time?
Here is my Script who transforms the target.

Finally here is my problematic object.

If someone knows a better way…
