Hello,
Please see these two screenshots, even when we resize the icon/Picture from the editor panel it doesn’t change it in the live site, the change applies only in Elementor preview..
Best regards.
The image size depends on the wrapper size it is inserted into. Just to test.
If it is SVG, try 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/l897ta
Then you will need to re-upload your icons in WordPress Dashboard.
