[Plugin: WordPress NextGen GalleryView] directional arrow out-sized

When the mouse is hovered over the slideshow the directional arrows show up.
The left directional arrow is normal sized but the right directional arrow is extra large and in the wrong place.

I am using the Weaver 2.2.6 theme and have the slideshow shortcode at the top of a page.
