Remove white area from multi column slider

Hi guys,
here is my slider:

if you click on the arrow to the right couple of times you will see the white area in the end. it is because the mask is set to 40% of the screen, since I would like just 2 columns to scroll per click.

so then it plays against me and in the end no matter how many slides I add there is still this white area.

do you know how I could fix it?

thank you
