Hi Adam,
When you try to cue the clip(s) in question, do you see a pop up dialogue on the switcher's touchscreen that says "Clip ID Not Found?"
The yellow triangle, depending on what message it's giving you, indicate either a missing clip, or an invalid clip. Missing clip suggests that the clip is not in the Nexio's database. An invalid clip could be caused by either an invalid format that is not playable by Nexio. Invalid clip could also mean that the file name is there, but there's no actual clip attached to the clip ID, such as the case with editors pre-naming the clips as placeholders, but the actual clip has not been edited yet.
The Red Octagon usually means the device lost communication with the switcher, or is busy.
