Ajax block in top – bug

Hello,
How can I disable your latest update: “Show ajax block in top if no space at bottom” on my website?

I want to show results on ajax block only at bottom because my search form is placed at the very top of the website, and when someone’s search for products on small height screens, the results shown outside of the browser viewport.

I use pro version of the plugin.

Thanks!
