Not sure if this is a bug or not.
I have sever Zooz ZEN34 wireless remotes. For each there are several Indigo Triggers, such as click up opens Z-Wave blinds, click down closes Z-Wave blinds, double click down turns off several indigo and Z-Wave lights in the room. Sometimes Device Groups are used, too.
Clicking "Show dependencies" on the ZEN34 remote does not show any triggers. Clicking "Show dependencies" on the blinds and lights and device groups that respond to the ZEN34 does show the Indigo Triggers that are triggered by the ZEN34, though.
Sample screenshots are below.
