Suppressing Blank lines causes repeat

I have an XML Template and have added code in properties help text behind all the BILL TO address lines to suppress null lines as follows:

<?if:BILL_ADDRESS1!=''?><?BILL_ADDRESS1?><?end if?>

<?if:BILL_ADDRESS2!=''?><?BILL_ADDRESS2?><?end if?>

<?if:BILL_CITY!=''?><?BILL_CITY?><?end if?>

<?if:BILL_COUNTY!=''?><?BILL_COUNTY?><?end if?>

<?if:BILL_STATE!=''?><?BILL_STATE?><?end if?>

<?if:BILL_ZIP!=''?><?BILL_ZIP?><?end if?>

<?if:BILL_COUNTRY!=''?><?BILL_COUNTRY?><?end if?>

However, although it has suppressed the blank lines - it is repeating the city, state, zip and country. I have uploaded an attachment to show this.
