Those screenshots are not the same results page, that looks different from the regular results page.
When I deactivate the Ajax Search Pro plugin and visit the results page I get this layout: https://i.imgur.com/GDPsFK4.png
Which is different from the screenshots.
That looks like either a custom made archive page of some sort or triggered by a URI param. Can you share what the URL is when you are on that modular page?
