This is an older (2012) YUI3 based slider. Off hand the easiest fix is to add some more slides (1?) or to increase their size to increase the overall height of the tabs (selector) on the left. Because the main image is floating, it's hard to set the height of the parent container since it's adjusted by the YUI3 slider widget javascript.
The easiest fix might be to add a 3rd slide or increase the 'selector' height to 1/2 of the total height. I am adding a bootstrap style fix for that gap between the tabs and the slide which will be in 2.3.8patch2 out in a day or so.
