Sorting Search | WordPress.org

Hello, we are using a search but the order is not alphabetical. I have tried to add shortcode of order_by=title and order=asc but it doesnt change. This order shown is also not the order on the directory categories so it appears to be random. The shortcode in use is:

[webdirectory-search custom_home=1 order=asc order_by=”title” search_overlay=0  search_bg_opacity=”100″ search_bg_color=”#c30101″ categories=1 location=0]
