$rscontent and $rscontent8 is site content for fields like company, department in 4 languages. It is not the fields the user enters, but the field description.The user enters their information in the white fields. That is the data that disappears when the captcha validation fails.
I remember when first setting up the page, on the order address entry page something needed to be done that the browser remembers those user entries. So that when navigating to the next page and then going back, all those entries would still be there.
