Those are from 2005 if I remember correctly. Isn't that the year that Navigator did the 56 day round trip from NYC that included the Norwegian Fjords cruise that Ngaire, Olivia, and others were on? That is they year that Diamond's schedule was cut short because the sale happened faster than anticipated.
In one place in the next they say Radisson instead of Regent. I think someone created a web page using an old page and posted it when they shouldn't have. Obviously this TA is not that familiar with the product.
