OrgUnits not sorted in pivot tables

Dear all, I know that in dhis2 manual there is a tip which says: “ The organisation units are then sorted alphabetically which will order the organisation

units perfectly according to the hierarchy ”, but after upgrading to dhis 2.20 this featuring is no longer works, it means that dhis2.20 is not ordering alphabetically from high to low orgUnit level. Is this a dhis2.20 bug as I tested on demo (DHIS2 App Hub) site and not working as well.

Any contribute I would appreciate,

João
