How to resolve message: Cannot change the linked status of an existing workflow step

[Tim Arthur]

Inherited a workflow which has a status option called Canceled. An issue in it needs to be reopened (moved out of Canceled). However, there are no transitions configured. Created a draft copy of the workflow. Linked Status box is greyed out, and under it is the message-

Cannot change the linked status of an existing workflow step

Not seen this before. 

Why is this and how can I resolve?

Thank you.

Found answer from 2018 post. Solved: Unable to add a transition in Jira (atlassian.com)

Pardon. Should have added that "add transition" as an option is absent from this status (Canceled). When clicking "Edit", I see the message as mentioned.

When clicking into View Properties > Canceled, the "Add outgoing transition" button is greyed out.
