Unable to change Position Target Strength on Physics Constraint

Create an actor blueprint, add 2 static meshes and a Physics constraint inside. Setup the constraint between the 2 static mesh components.
Drop the blueprint inside the scene.
In the details panel of the actor blueprint, navigate to the physics constraint and try to change the “Position Target Strength”. If I add a value other then the default value, 3 lines appear.
