First of all thanks for choosing our Theme, we are glad to be you in the WoodMart WordPress family :-).
As stated in our theme description page, all images including SVG icons are not included in our theme package. We are not allowed to resell them with our theme due to the restrictions of their license. But you can find almost all of the theme on this website https://www.flaticon.com/
And for the SVG not working please provide the URL of the website to check it myself and help you out accordingly.
