“A core incompetancy of Nikon are its "Settings Banks" system used in many of its cameras, including the D500. Instead of a simple U1 U2 etc. setting that just recalls all your saved settings at once as on the D750, Nikon uses two sets of banks (the "Photo shooting menu bank" and the "Custom settings bank") to save camera setups. Sadly both of these two banks together only save 2/3 of what you need, and don't save important items like AF settings”
