With the help of ESRI's Matthew Twietmeyer I've deployed the election Management Solution and need to add a field to the ElectionGeography hosted feature layer (Election Day Metrics table). I am the owner.
I open the item details, go to Data, and select the Election Day Metrics table.

Strangely, I am able to add a field to the ElectionResults hosted layer (ElectionResults table).
Any tips on how to accomplish this or why I don't see what I'm expecting here?
