FBW A320NX - No power/displays after Sim Update 3

Hi there, I tried flying KCVG to KORD yesterday and loaded the IFR flight plan in the world map. When flying the approach, the aircraft never picked up the localizer, so I was visual the whole way. This was my first flight since Sim Update 3 and I had just updated to the developer A32nx (I hadn’t updated the FBW mod in a while).

Am I doing something wrong, or is the ILS system broken? In the past, when the flight plan was pre-loaded, all I had to do was press the localizer button and the approach button at the appropriate time. Perhaps I’m missing a step now with the updates.
