Conflict with EasyBootstrpShortcode plugin

Hi,
I installed Quick cache and instantly got speed boost. Amazing improvement.
However, when I revisited the site, the colors of key icons had been stripped off and all that remained was a black icon, without any customization.
Please can you advise the setting to maintain the color of icons that come with EBS-easybootstrapshortcode

The site and EBS icons were working perfectly before installing Quick cache.
