Remit To Address display issue

Hi Team,

The address at customer/Supplier/Remit to address shows P.O Box Number in Address Line 1, even if we try to change it to appear n Address line 2.

For example

Address Line 1 : ABC Company

Address Line 2: P.O Box : 112345

When I try to save the address and USPS validation is triggered, it saves it to below

Address Line 1 : P.O Box : 112345

Address Line 2: ABC Company

Thanks,

Hetal
