Cannot add fields to a newly created step

[mattwalo32]

There's a bug in the Dashboard Management page such that you cannot add a new step with fields. You can add a new empty step with no fields though. This is because there seems to be an issue with key generation for fields on new steps.... I.e., we're not generating for fields before creating a new step. This results in an error on the frontend.

This should be a pretty easy fix in the backend code.
