This was noted in 2021, but is still there! Correct freq is 117.75 - please update the chart.
I am using FSLabs A320 series with Prepar3D v5.4.
117.75 is not even a valid localizer frequency. ILS goes from 108 to 112 MHz (first valid localizer frequency 108.10 MHz, last valid localizer frequency 111.95 MHz).
117.75 would be a VOR of some kind.
Here are the official ENAV charts (downloaded from autorouter in this case, not sure if they’re available publicly direct from ENAV; if they are, I couldn’t find where), showing IVRN’s localizer frequency is indeed 111.75:

Thus, the Jeppesen charts provided by Navigraph are also correct, and there is nothing to fix.
