Hi Usuario1988,
Actually the space in your phone number is causing an error for w3c validation. The content is displayed from your theme folder -> inc -> structure -> header-extension.php. You just view our demo site and its has no error.
From here you may modify the code but We recommended not to change the code because if you change the code then while updating to our new version all your customisation code will be lost. So better make child theme and first unhook the functions and the edit the code.
