Hi!
Unfortunately the results page contents printed are not affected by Ajax Search Pro, that is a theme controlled feature. Most themes use the the_excerpt() function to print the post excerpts on the results pages. The weir symbols you see there is an automatically generated excerpt, which contains parts of a non-executed shortcode for some sort of social icons snippet.
I recommend checking your theme options, some themes have options to change what field is displayed on the results loop. You can also ask the theme author on how to change that, usually it is very simple.
