Go to MY INFO and Edit (blue pencil to the right) your Address Info.

It is best to completely Delete and Re-Enter the correct address.

See screenshots.

Thank you for your reply. I tried this suggestion but unfortunately, it did not change the "check this entry" review. Would this have been an error on my part when registering?

When you Edit your Address Info, change the 'Type of Mailing Address' to 'US Address', then delete everything.  Then change it back to 'Foreign Address' and delete everything.  Then change back to 'US Address' and enter correct info.  This is a program issue; not your fault.  Let me know if that works.. thanks for your patience!

Thank you so much. This worked! Greatly appreciate your help. Kind Regards, Dearbhaile

Worked for me as well. Thanks!
