When a report appears without an ‘Edit Content’ icon on a dashboard widget, it can be the manifestation of an issue with the list or report generation, even if the list or report appears to display correctly.

This can be caused by a broken Workflow Stage field.

Known causes can be:

1. Workflow Stages for a subflow aren't defined on the parent - https://hi.service-now.com/kb_view.do?sysparm_article=KB0743084
2. The instance was cloned without all Workflow tables and the platform isn't able to map the Stage integer values to the display value

1. Define stages on parent Workflow, not the subflow
2. Re-clone the instance with all workflow related tables
