Welcome to OSM, and thanks for your contribution.

The warnings that iD shows are not necessarily issues which can be fixed blindly - you need to look at each on a case-by case basis.

In this edit you changed 
https://www.openstreetmap.org/node/2405398627
from being named "Costa Brava Bistro" to a branch of a British coffee chain. This isn't correct - let me know if you need help fixing that.
Also it is Wilmington Drive, not Wilmington Street :)

happy mapping!
