That's the Open Graph tag for the site/page description primarily used by Facebook. Not being familiar with the template you are referencing, Open Graph text is derived from actual site content or fields.
Did you check in Site Settings > Search Engine Optimization > and input a new description for each page? The only thing I can think of is if the description field is left blank on each page it may be defaulting to the template's description.
I checked my GoCentral store and do not see any Open Graph tags in the code -- but my test site is not published so that could be why.
Do you have a URL for me to take a peak at? 😉
