Why hierarchy not displayed properly in main view but is appearing properly in local view RSRT?

Hi all,

Few days back I changed the data source of my private view. Previously the hierarchy was formed properly in rsrt (query 2CCSUBCTRG). But after doing changes, the hierarchy is not generated properly. I replicated my CDS view in local views and ran rsrt with local cds query (2CZCSUBCONG). There hierarchy is properly formed. I raised a ticket https://support.wdf.sap.corp/sap/support/message/1870125571 but still it has not been resolved. Can anyone help? The system is ER9.
