Display Glitches

Hi,

I was testing my site on mobile and realised there are a couple of display glitches on my site. All of these involved the alignment of Icons. As you can see in the snapshots, the icons are not aligned properly in the center, but more towards the right. Its already set as aligned to center on the settings. It looks fine on the desktop view but not so on mobile.
Is there any code that can fix this? Thanks.
