M Audio Uno question

Im using M Audio Uno with the RH v3.1.4 Image v1.6.0
We use Cuelab to trigger cue's in the RH cuelist. The first thing i noticed was that when u start up the RH with the device plugged in, it doesnt show anywhere.

After programming, matching times and follows and walking through the show we went for dinner, but when during the show the first cue should have been triggered nothing happened on the RH. The device was recieving from cuelab, led fading idle but nothing happenend. Does anyone why this is? There could have been 3 hours between the dinnertime and the start of the show.
