Unable to check in .sda file for ess in the track for NWDI

Hi Gurus;

We have created the track and added the three dependencies along with PCUI_GP.We have imported these into the track.

However after placing the .sda file for ess under Jtrans/CMS/Inbox folder and adding it as software component to the track through Landscape Configurator we are unable to get the ess component under the checkin tab of the track in CMS. Please suggest why this is happening?

Regards;
