I tried to land on 1L at KLAS a couple days ago and the FBW320 didn’t pick up the vertical guidance on the ILS so I hand flew it down from 10 miles out. I don’t know if its a problem with 1L but the FBW team are often tinkering with things and sometimes stuff just doesn’t work. It also wouldn’t be the first time I saw no vertical guidance on ILS approaches for a couple days. Maybe ask over on their Discord?
