I had this exact same issue on all my sites that were using the SVG Safe plugin. Either they were super tiny or didn’t show up at all. I reverted by to the previous version using the WP Rollback plugin and it resolved the issue. Hope they fix this in the next update.
I’m using the Divi Theme on my wordpress sites and the images will show up fine if they are used in the background but will not show up correctly on the image module, or the menu module (for the logo).
