The pads are not wrong in performance mode, they actually match the layout of many other DDJ controllers. What you're referring to is the fact the functions of the pads when used with rekordbox don't match those of the labeling on the hardware itself.
Please refer to this document for the mapping of the controls -- and if you're still not content, you're always able to edit the mapping using the MIDI editor within rekordbox.
