Hello @Donald Paterson
Welcome to the Atlassian Community!

This issue seems to be related to a misconfiguration in the project settings (could be something related to the Issue Type Scheme or either the Fields Configuration Scheme)

Are you the product administrator? Are you able to share a screenshot of the Issue Type Scheme being used by the project?

Thanks,
Eugenio
