When working with a shared event, it's possible for the agency to share the deal with your Artist account.
If you see this Agency deal-logo when you are in the event, that means your Agency is sharing it's deal with you.
Agency Deal page
The Deal page is a copy of the deal your Agency made for this particular event. You can find the deal type, and the fee, and the bonuses, etc.
You will also find the artist statement. The Artist Statement will display a simple overview of your deal outcome.
You can only view, you can't make changes.
Deal page
The Agency Deal page is different from your own deal page. You can use Deal page, that is separate from the deal the Agency made.
You can use Deal Page for you own deal and calculations and to track costs for, for example, crew, etc.
