Landscape Spline w/ Reserved for Spline Layer deforming landscape permenantely

While using Splines with the new Landscape Layers, the landscape deforms as expected.
But if you move the spline horizontally, instead of just vertically, the landscape will deform “permanently” (you can still delete the Spline Layer, but you get where I’m going) and will not go back to the original form, even with a base layer.

EDIT: Toggling the layers visibility ON/OFF sometimes work

hey there! I’m having a similar problem. Did you come up with a solution?
