In a Doc library in one of our sub sites, there are multiple OOB Approval workflows that get started manually.
The Power User who creates these created an additional one this week (there are 5 other Approval workflows associated with the lib). There are 6 instances of the newly created workflow currently running, but the associated status column never appeared in the doc library.
It is not just hidden in the view, it is not one of the selectable columns, period. The workflow is working fine in all other respects. I opened the lib in SharePoint Designer and it does show the workflow as associated.
