Hello,
You are not reading wrong! Here is the explanation: we changed the dxomark and sharpness scoring system last December (for further information you can have a look at DxOMark's Perceptual Megapixel on this page:
www.dxomark.com/index.php/Publications/DxOMark-Reviews/Looking-for-new-photo-gear-DxOMark-s-Perceptual-Megapixel-can-help-you).
For this reason, previous reviews using the old scoring system are now indicated with a banner. This one was actually missing but that should be fixed soon.
Sorry for that!
Regards,
