Issue in line plot while saving in vector graphics

I had a matlab figure, it contains 4 lines. When I'm trying to save as pdf/eps/emf, one of the line's resolution is going crazy. I'll attach the matlab figure and pdf file also.

Please do needful.

f1 = openfig("para_sub_2D.fig");
print(f1,"pic.pdf","-dpdf","-r300")

The lines in the pdf are appearing fine for me (R2021a on Win 10), as clear as the lines on the figure.

See the screenshots attached.

I recommend using exportgraphics. The results below were produced in R2023b.

open para_sub_2D.fig
exportgraphics(gcf,'mypic.pdf')
