[Plugin: Social Sharing Toolkit] pinterest button size!

Hi there!
I’m using this plugin on my websites: picpuffin.com and invisiblegentleman.com and experiencing different issues:

– at picpuffin i’m using the blog in blog plugin so everytime I click on the share buttons I’m sharing the blog-in-blog page called blog and not the post inside which I placed the social sharing kit shortcode,

– at invisiblegentleman everytime I had the pinterest button it looks great on the blog front page but inside the blog post it comes on an huge size, occupying the page from side to side.

And that’s it!
This is a great plugin and I just need some help in figuring out how to solve this issues.
Thank you in advance!
