Problem with mesh displacement visualization

I am dealing with multuphysic problem and wth displacement of mesh between the iterations.
At the end of simulation I can see the variable the displacement intensity in the mesh on paraview as results, but I would like also to better visualize the displacement using the “displacement Magnitude” on Paraview, But when I digit the magnitude (whetever the value) I see no differences. ( I applied the displacement box). How can I solve? thank you!
I am using Paraview 5.11
