Counter Not Counting & Problems with Icons

I have just purchased the PRO version. I'm using version 6.0 and I'm having a few issues that I'm hoping you can help with.

1. The counters are not animated.
   
2. When I upload an image for the icon, it's not centered - I have to make the image the size of the column to get it to center, but then it looks too large on mobile.
   
3. I have tried to create CSS but it doesn't seem to make any difference to the look of the counter.
   

This is the page: https://www.childrenshospital.ab.ca/your-impact/donations-at-work/pediatric-critical-care-transport-team/
The icon that I want to center is the first one. The 2nd & 3rd Icons are the image that is the size of the column.

Please let me know if you need any further info.
Thanks.
Jen
