Display Problem with Order Details

[Ollie]

For some reason, I'm not getting the correct display in the fax field when I go to Sales > Orders > Order  Details. See attached screenshot. Which template should I restore to fix this problem? Or is the problem being caused by something else?

You need to check here:
admin/controller/pages/sale/order.php
or
admin/view/default/template/pages/sale/order_details.tpl

Look like there is not closed tag or broken HTML
