If a Checklist Template has been recently added, modified, or deleted, the options in the Checklist Template dropdown field on Jira issues may not reflect the most recent changes. It can cause the template feature to malfunction (i.e. when the template is selected in the Checklist Template field, the corresponding checklist won’t load). To address this:
Find all issues with a value in the Checklist Template field.
2. Bulk update the issues to clear the Checklist Template field from those issues.
3. Make any desired edits to the Checklist Templates. This will trigger the templates to re-sync with the Checklist Template field.
