Issue Description
You try to approve a segmentation and get the error message of "No possible draft" even when there is a draft in place.
Issue Resolution
This error message can be a little misleading, as there usually is a draft in place.
Check to make sure that segments in the draft have smart list filters in place and that there are no empty values in the smart lists. An example of an empty value would be "First Name is ____" instead of "First Name is Joe."
