Dissapearing Dispalcement settings?

I seem to be missing a lot of the displacment settings when loading megaScans surfaces. Dispalcent streangth, contrast I have none of these my Ui looks comletely different and im not sure what Im doing wrong. Even more frustrating is I can get them to work ( still mising the controles) but they wont show up on landscape meshes but will show up on static meshes. Im very confused.
