Offset Alignments Go Crazy

I have a centerline alignment with two offset alignments that reference it (road edge).  At the curves throughout the 3+ mile segment I manually added widening to the offset alignments at the curves.  I now need to go back and add additional curves to the centerline alignment.  I'm trying to do this by adding additional PI's to create a new tangent where I want the curve, then deleting this tangent and adding in the new curve.  When I delete the new tangent sub entity my offset alignments get cut off at end of the alignment (where I deleted the tangent).  This causes all of the widenings I had created to be bunched up at the section of remaining CL Alignment.  When I build a new curve through the deleted portion and re-establish the alignment to its full original length the offset widenings do not re-associate to their original stationing (they remain bunched up at the first few hundred feet.

 

Is there a way to add curves to the alignment without losing the stationing for my curve widening on the offset alignments?  I attached a screenshot of what happens to my offsets (red) when I delete a section of the CL alignment, the widening remains all bunched up when I reconnect the original alignment.

Don't delete the tangent, use Free Curve Fillet and select the two entities you want to fillet then enter the radius.
