First of all thanks for choosing our Theme, we are glad to be you in the WoodMart WordPress family :)
You need to open your SVG icons file with some editor like Sublime Text or default system text editor and add height and width attributes to your <svg> tag like it is shown on the screenshot https://gyazo.com/83fd36b0bb9628bb1aed2bd3d5d063c5
As I mentioned in my previous reply Please open your SVG logo file with some editor like Sublime Text or default system text editor and add height and width attributes to your <svg> tag like it is shown on the screenshot https://gyazo.com/83fd36b0bb9628bb1aed2bd3d5d063c5
Then upload the file back to the dashboard and set as the logo. This will fix the issue.
