Can someone help me with this error message?

Data source error: Column 'DESCRIPTION' in Table 'IssueTypes' contains a duplicate value 'A small, distinct piece of work.' and this is not allowed for columns on the one side of a many-to-one relationship or for columns that are used as the primary key of a table. Table: IssueTypes.

Seems it is something I've done in Jira. It worked before and I haven't changed anything except the amount of data entering into Power BI.

Thanks!
