button not displaying properly

Hello there, couple of issues with the plugin, great plugin btw.

One of the buttons is not displaying correctly, I tried different settings and clear cache but no luck.
https://www.designlinesmagazine.com/advertise/

On the right column there’s a button to download the PDF that is displaying only with a small purple square. Should be different.

Also in some pages, like
https://www.designlinesmagazine.com/the-best-stores-in-toronto-to-buy-a-bed/
at the bottom there’s a related carousel and in mobile the rendering is wrong, instead of full images, the rendering is creating small boxes.

Any suggestions?

Thanks
