Social Bar buttons

Hello! I need some help with the top right social bar of my company’s website. I didn’t make the website and I don’t know much about HTML or CSS… and our web manager is very irresponsible, so, here is the problem, when you click on the Twitter or Instagram icon, the buttons doesn’t take you to the Twitter or Instagram profile of the company, instead, those buttons open the search bar. We told about this problem to our web manager, but he just keeps ignoring us. I’ve been studding HTML and CSS but I can’t fix the problem, please give me a hand and tell what I need to do to resolve the problem. This is the website https://www.lebrunyachts.com
Any help would be appreciate it.
And please forgive me if my English is not good enough.
