757/767 do not automatically display left and right ILS frequency on the 'map' mode. You set the center ILS and it tunes the left and right ILS. It's up to each pilot to then switch their nav display to the ILS mode to verify the correct frequency for their respective ILS.

Randomly the center ILS will not correct tune the left or right ILS. It's a problem with what the center ILS is displaying for a frequency vs. what is actually being tuned. You then have to adjust the center ILS frequency selector until the left and right ILS's have the correct frequency.

SOP's cover this - tune center ILS, verify on respective nav display by selecting ILS mode, verify via morse code.
