Placeholder Text In The 'address_2' Field


[color=#000000]I can't find a solution for this. Hope anyone can help me out. In the checkout page, when customer is filling up the form, even if customer leaves the 'address_2' field blank customer gets the placeholder text 'Apartment, suite, unit etc. (optional)' as if the [/color][color=#000000]customer[/color][color=#000000] would have filled it up.[/color]

[color=#000000]How can I fix that?[/color]
