Control point edited curve not lofting in grasshopper

I have discovered an inconsistency when creating a surface from two curves,one of which is control point edited from the other.
Grasshopper will not create a surface or a loft from the two curves

If I bake the two curves to Rhino (Version 8 (8.18.25076.15002, 2025-03-17),
I can use PlanarSrf or Loft successfully.

Data Tree differences :bangbang: Flatten the Loft input.
