A macro that has no actions will not do anything even if you trigger it.
You will need to add some actions to the macro by editing it. Double click on the macro in the Macro column to edit it (or just click on it if you are already in Edit mode).
You can add actions by clicking on the New Action button and selecting an action from the action selector. Or you can choose Edit ➤ Insert Action menu.
If you continue to have problems, contact support.
