SCUP updates are not publishing in SCCM console

Hi 

We have SCUP (5.0) for 3rd party updates and doing the deployment via SCCM 2012. Recently we noticed that updates are publishing in SCUP and same thing is not getting updated in SCCM. I tried to create an ADR for the deployment of flash player updates and not able to see the latest updates in preview mode. Last update visible is 21.0.0.213.

Any help is appreciated.

Thanks!!
