Grid tiles vanish when I click on the right or left margin of the page

Ajax Search Pro is working beautifully so far. I only have one issue I would like help with.

When I load my results page I can see all the grid tiles and it looks great. I’m using isotopic layout.

But if I were view the page, and accidentally click on the left or right margin of the page, in the white space, to either side of the grid, the tiles disappear.

In the attachments I’ve put a screenshot. In the yellow highlighted area, this is the place where I clicked, and when I did the tiles vanish. They come back if I select a checkbox option.
