Hi,
Do you mean, that the footer is visible on the live results list description field?
For that, you can try this option – it may fetch the shortcodes and remove it’s contents properly.
If the text is showing up on the results page (after hitting the enter or magnifier button), that can not be controlled by the plugin – that page layout is printed via the theme. Some themes have options to change what exactly shows up on the results page, there might be adjustments for it in your case too.
