This is likely due to role privileges missing or mis-configured.
If there is more than 1 role privilege missing, a user may see several lines of warning banners in the FlexReport editor. One for each missing "FlexReports" privilege. This is expected behavior for users who do not have permissions within their role.
To resolve, please check the roles for that user or group and ensure that desired permissions have been granted. The local administrator for the Tanzu CloudHealth cost application can grant these. The CloudHealth Technical Support team cannot grant users permissions beyond those assigned by your company admin.
