When I create a new Kanban Board with sample data, I receive the following error:
Error
Unexpected failure occurred. Importer will stop immediately. Data may be in an unstable state: expected one element but was: <com.atlassian.jira.issue.fields.config.FieldConfigSchemeImpl@9b0f3132, com.atlassian.jira.issue.fields.config.FieldConfigSchemeImpl@9b0f34f3>
After the error, I don't see the board displayed. I tried create another board and same outcome. I also tried restarting my computer, same outcome.
It looks like the board is somewhat created, when I add another board, the Project Key is incremented.
