As Scott pointed out, it looks like your reflections are currently not reflecting anything from above.
Instead of the bleak blue sky, maybe opt for one of the preset physical sky settings. I'm partial to Friendly Afternoon. Make sure to tick 'Use ARCHICAD Sun Position' to keep your own sun direction etc settings.
In detailed settings go to 'Environment > Physical Sky > Compositing' and make sure Sky Reflection is ticked.
Also check at the bottom for 'Options > General Options', make sure Reflection is ticked and set Ray Treshold to 0 so all reflections are calculated.
