It used to be that you could get a print of a photo in the paper by going to there offices and ordering one. Now it appears that they send the photos that they publish to some other company
www.newsprints.co.uk for people to order prints. The ToS imply that they share the profits with the photographers.

It could be that they've just forwarded all the photos they print onto the printing company.
If I were you I'd query whether they have made a mistake, and how much you'll get from any sales.
