Don't use "Do nothing", it's unnecessary. Also, you don't need the AND in your conditions. By default the conditions need to ALL be true in order for the Actions to run. On top of that, you probably want to use an OR as well, and check if the order is "smart" or "move". Smart = right click, Move = pressing the Move ability or using it's hotkey (M).
If after that it still fails, try displaying text messages throughout the trigger to find where it goes wrong. For instance, you can Pick every unit in TransportingOGroup and display the name of the picked unit or create a special effect at it's position, this will tell you that the Unit Group is actually picking the Zeppelins properly.
Try doing something like that throughout the trigger and it will help narrow down the issue.
