Try removing these lines from the DisplayPlot {} section:
qproperty-line_style1: SolidLine;
qproperty-line_style2: DashLine;
qproperty-line_style3: DotLine;
Since the lines are also in Frequency plot and Vector plot sections, that
change should not affect them.
It might mess up a Time plot, but then you can just add those lines to that
section to fix it.
