Cardinal points in cant Alignment getting changed with revised horizontal alignement

Hi,

After designing horizontal alignment with 100 curves, i created cant alignment as a child under horizontal alignment.

Then i clicked Define all option and used equilibrium equation method. Many of the curves i defined cant by editing speed and applied cant manually.

And finalised all the 100 curves.

Here my Problem is if i change the transition length or radius of the one curve, the cardinal point location of all subsequent curves are getting changed.

For example if i change the curve parameters at Curve number 3, the cardinal point location from curve 3 to curve 100 are getting changed.

I can Redefine cant alignment with define all option. But i need to change again all the curves wherever i made the changes manually.

Can anyone sort out my problem?
