Created a child theme and some css elements are not working

Hello,
I just downloaded the child theme(generatepress). After activating some of the CSS elements are not working.
The one I am referring to can be found on this page
https://mensprimp.com/what-does-beard-wax-do/

When you scroll in the middle of the page and you will find the "pros" and "cons" table.
the table has been created using mighty pros and cons plugin.
It used to show "thumbs up" and "thumbs down" image but after activating child theme it's only showing a square.
Can someone give me a hand here.

Also please let me know how to embed screenshot with the call.

Thanks
