It should contain one item: customCaseRoles : owner:1,manager:1,supplier:2 Remove supplier from the Case Roles, save the changes, add it to the Case Roles again, save the changes, close the case and open it again. Actual result The Metadata Attributes contains two items: customCaseRoles : owner:1,manager:1,supplier:2 customCaseRoles : owner:1,manager:1 Every new change in the Case Roles will increase the number of metadata attributes. Expected result The Metadata Attributes contains only one item: customCaseRoles : owner:1,manager:1,supplier:2 There is always only one item generated in Metadata Attributes.
