Before configuring any progressions, you should review the
list of statuses that are available for that module. Using
the Issues module as an example, you can hover Issues in the
main navigation bar, and then select "Config"
Whilst viewing a list of statuses, click the recycle bin
icon from the far right. If the icon is unavailable, this is
because that status is currently being used by records in
the system. You should run a search for records in that
status and progress/edit them into a different status. You
should then be able to delete the unwanted status.
