Hello,
The page may have a customer header that is why you may edit the default header and you do not see the changes as page is configured to display custom header.

Another reason why you do not see the changes is the cache.
As for the SVG problem. There may be two reasons:
1. You need to open your SVG icons file with some editor like Sublime Text or default system text editor and add width=”31″ height=”40″ attributes to your <svg> tag like it is shown: http://prntscr.com/m4n0qw
Then you will need to re-upload your icons in WordPress Dashboard.
2. Chrome browser needs the image to be almost of the same size as the containing block is. Try different SVG sizes.
Best Regards
.
