If you have USS -> Catalog -> SDM approach, then only Closed status in SDM syncs back to Catalog (there by reflects in USS too).
This is per current design.
I have seen some customers implement a PAM process (which can be kicked off via an Event in SDM, say status changed from blah to Resolved), to sync the SDM ticket status to Catalog ticket appropriately.
But at this time, Closed status in SDM is the only one that syncs back to Catalog ticket using the native SDM -> Catalog's catalog sync daemon integration.
