I have a client that runs a property management business. Their site is built on wordpress. However, the template is not responsive, so they installed the WPtouch plugin to create a mobile-friendly version of the site.

Is it bad if both URLs are showing in the SERPs? Duplicate content issue? If so, how do I correct this?
