Wordpress / W3 cache help

Please see this review page on a website of mine: goo.gl/9zbrrs

There are problems with the review box at the top right, the social icons near the bottom of the post and the email subscribe / sign up box.

I've attached screen grabs of how they look and how they should look. The problem is caused by W3 cache. When I either disable the cache or view the pages when logged in they look fine. But when I enable the cache plugin and log out they look like this which is how my visitors are seeing them too.

I believe there will be a way to find out which part of the cache is causing the issue and exclude the script for these items in the settings. I just have no idea how to do it. I'm sure its fairly simple if you know how?

For the hourlie I would like someone to fix the issue but also to show me by a screen cast recording (with verbal instructions) how they did it so I can try learn from this should I need to fault find a similar issue in the future.

EDIT / UPDATE:
I have found the issue is to do with the minify settings. If I disable them then the site works fine. However it adds 2 second to the already slow load time of my home page and a second to an internal page I tested.

Note to applicants
If your not sure what the issue is from the description above and the pictures then please don't ask me to chat for further info. I'm looking for someone who know W3 cache and wordpress well and will likely know the solution to this as soon as they see my post.

PS: I have disables minify setting for now so that my site works well for visitors. please refer to the pictures provided to see the issue.
