Address Alias not auto incrementing for new customer

[treyj45]

Hi,
When I add a new address to an account that already has addresses, the new address form is pre populated with My Address, which is already used by default.  It used to auto-increment and create a new address name.  I found this line in address.tpl
 

{if isset($smarty.post.alias)}{$smarty.post.alias}{else if isset($address->alias)}{$address->alias|escape:'html':'UTF-8'}{elseif !$select_address}{l s='My address'}{/if}

Im not sure why this wont work, does anyone know where I can find where the address alias is supposed to change for a new address so I can try to troubleshoot? Im having difficulty finding where.  Thanks
