Change of address post I130 submission

[ravbp 0]

I am trying to change my address using: https://egov.uscis.gov/coa/addressChange.do

I have recently moved from a large apt building to another large apt building. When I get to the "Mailing Address" section, I click that it's the same as the new address entered above. Then a pop-out box comes up asking me to confirm the address - when I hit confirm, I get the following message:

WARNING: The U.S. Postal Service (USPS) system has found multiple addresses matching the address you entered. Please review the address and make sure the street, city, and state are correct. Please also include the apartment or suite number so the USPS can deliver the mail to the correct address.

I have entered the correct street, city, apt number, etc. The only way I can leave that box is X'ing out. then when i got to hit submit it tells me:

Data Entry Errors

**The Following Fields Are Required.**Street Number and Name in Mailing Address is Required
City in Mailing Address is Required
State in Mailing Address is Required
Zip Code in Mailing Address is Required

Has anyone come across this?
