• Scroll to line number 264. where a function outputFilter is declared as "function outputFilter(refinementName, refinementCount, refiners, method, aClass, showCounts) {".
• on the next line insert the following code:

if(refinementName.indexOf("|") !== -1){

refinementName = refinementName.split('|')[1];

                refinementName = refinementName.trim();

}
