address information problem

hi,

I have a customer who keeps returning to our website. his address has the village name 'street'
unusual I know, but for some reason the website wont accept it. when he puts the word 'street' in, the website changes it to 'address'. I've tried manually editing his address information on the back end - I can only get it to say 'street' if I put a comma after the word, otherwise it stays as 'address'.

any ideas?

kind regards,
Tanya
