Resizing custom iconbox icon

Hi! I need to resize my custom iconbox icon, but the layout isn’t working correctly.

I looked up how to replace the iconbox icon here https://kriesi.at/support/topic/iconbox-is-it-possible-to-add-our-own-image-to-the-icons/, and then looked up how to resize icons here: https://kriesi.at/support/topic/adjust-icon-box-circle-size/.

However, it looks like the custom icon is running into the iconbox text slightly, causing the text to misalign (see link below to see what I mean). See the link to an image showing how the iconboxes should ideally look–all the paragraph text should be flush left.

I’ve looked all over the forums but haven’t been able to find a solution. Could you please help? And Happy New Year :) .
