Single Line Address probably not working!

In the following function, you set $afields to an empty string, but that's your array! That means the array will then look wrong. I'd bet that this function won't work.

function theme_addresses_singleline($afields) {
  // Check if its a valied address
  if (empty($afields)) {
    return '';
  }

  $afields = '';

  // Add the streets
  if (!empty($afields['street'])) {
    $afields .= $afields['street'];
  }
  ...
