7.3.0 Groups Recommend block Pinterest icon

Hi,

I just upgraded to 7.3.0 from 7.2.1 and checking out the various parts of the website to see if anything is amiss.

Noticed the following when going into Groups:

I had my mouse cursor on top of the icon to see what it is, it shows it's "Pin It".

Any ideas why the icon isn't actually showing up?

Are there any other icons supposed to be there?

Thanks.
