Duplicate expenses

Eddesignlab

A couple questions:

1. How do I delete a duplicate report as the admin or does the employee have to delete?
2. One of my employees is saying that her expense are coming in twice - once when she uses the receipt forwarding and again when they import from Truist (our credit card vendor) how does she delete one and stop that from happening
3. Is there a way to merge multiple expense reports into one?
