I’m not overly familiar with exporting sites out and how they are re-rendered, playing around with what I could though, I found that from inspecting the .com website, that by changing the 33% width of the icons div block you created to 32%, that they all fitted in.
Probably not the most ideal solution, not sure, but perhaps a compromise for the time being. As I can’t replicate this, it may not actually work, but hopefully you have some luck.
