Spline generate LogPhysics on build

UE4 4.4.0

One of our level is making use of Spline Actors and on build it generates one line like below per actor:

LogPhysics:Warning: FBodyInstance::UpdateBodyScale: Want to use NegX but it doesn’t exist! /Game/Maps/TheCoalMines/2-3_Catacombs_geo.2-3_Catacombs_geo:PersistentLevel.Landscape_0.SplineMeshComponent_0.BodySetup_2742

What causes this and how to fix?

Thank you,
