CS-Cart product filters shows two layouts with grids on product listing page


I am using cs-cart version 4.0.1, and have made changes since past 3 to 4 months in my site, but now when I try to filter products by any attribute(price, designer or size), then results appear with two product list page layouts on same page with two grids, and filtered results show up in below grid.

Can somebody please let me know what might be issue occuring or any idea, please ?
