I am using the Paraview 5.6.0 64-bit. I can successfully load my vtk file and visualize the data. This is what I see in the layout window
I saved this visualization by going to
File and then
Export Scene. I noticed that when I choose either PDF or EPS format, the location of the legend in the generated file changes to the lower left corner.
This issue has been apparently reported before too at https://scicomp.stackexchange.com/questions/27558/color-legend-location-in-eps-files-exported-from-paraview-v5-4
