Trying to delete social media icons at bottom left corner of a CorporacyPro site

Hi,  I have recently purchased the Corporacy Pro theme (and loving it!!)  and use it for my site at:  https://www.bouncy-castle-web-content.com   Unfortunately, I cannot delete or change the three social media icons at the bottom left hand corner on the home page.  (They all point to Catch Themes)  I have edited the footer on the bottom RIGHT hand side with no problems.  I would be very grateful if someone could show me how to edit or delete these three social media images (Facebook, Twitter, Instagram) on the bottom left.  Thanking you.  Mark Jerram  (Catch Themes Customer)
