Hello.
In the integration there are two conversion variables that you define
- Campaign ID
- Broadlog ID (I believe you have renamed this to Delivery ID)
Example screenshot:

The Data that is consildated from Adobe Campaign over to Adobe Analytics is on the basis of Campaign ID. It is not tied to the Broadlog ID (Delivery ID)
Here is your screenshot:

The highlighted values are the Campaign IDs, the numbers following it are the metrics (scheduled, processed, sent, clicked, etc). You can note that only the Campaign ID is sent over with the metrics, and not the Broadlog ID.
This is why when you are running the Delivery ID report with the metrics, you are not seeing anything (as far as I can tell)
