Tessellation on Landscape still on even though turned off?

Hi, I have a landscape I am making and I have tessellation turned off for performance purposes. However when I am in wireframe mode I am noticing tessellation happening anyway, even though all of tessellations settings are turned off in the output and no tessellation is selected. I also have a constant at 0 for World Displacement and tessellation, yet it’s still creating tessellation on runtime? Please help. :frowning:
