Unwanted Landscape deformation offset when deforming landscape with splines in different edit layer

When deforming the landscape based on a spline (using both blueprint and landscape splines), the landscape should “snap” to the spline. However, if the spline is placed or used in a different landscape edit layer than the initial deformation, the landscape will have an offset equal to the height of the landscape’s deformation before the spline was placed.

I expected the landscape to deform to the same height as the spline, not to create an offset that’s dependent on the deformation on other layers. It should preform as it does when the deformations are in the same edit layer.

What happens:
