Duplicate Content URLs

Hi

I’m using Slick Social Share Buttons on my site, and it’s awesome, works really well.

However, when I run it through Google’s PageSpeed Insights, the report shows as “High Priority” that I should serve resources from a consistent URL, and it indicates that I have duplicated content coming from different URLs associated with the plugin, namely

http://platform.twitter.com/widgets.js
http://platform.twitter.com/widgets.js?_=1360838071931

and

http://platform.linkedin.com/in.js
http://platform.linkedin.com/in.js?_=1360838071931

So I’d like to know how, if possible, can I correct that.

Thank you for your time
