This happens if only a single workflow has the tag "schedule"
Steps to reproduce:
1. Remove tag "schedule" from the workflow "Fast"
2. Create a scheduled event (select the workflow "Process upon upload and schedule)
3. Open the tab "Workflows" in the Event Detail modal for the scheduled event created in step 2
The currently selected workflow is not displayed.
The currently selected workflow should be displayed.
