Min-height setting creates too much white space

Hello–

This plugin works responsively except that at narrow browser widths a hugh expanse of space displays between it and the next batch of content.

Inspecting the page I see a class=”smooth_slider” that includes style=”min-height: 600px;”

I cannot find where this is coming from. I cannot find it in settings, nore in any of the three plugin CSS files. Attempts to override it in Custom CSS with
#smooth_slider
{ min-height: 100%; }
and variants seem to be ineffective.

Any suggestions welcome.
Thanks
