Issue Adding a Business Workflow in BPM Process Diagram from NWDS

Hi

I am trying to add a workflow from the backend S/4 system into my BPM scenario using NWDS 7.31 . When I use the search console in my BPM I can see lot of workflows from the S/4 but I don't see the one that we have created as a  custom workflow , a copy of the standard workflow ( WS01700048 ).

I am not able to see the standard workflow mentioned above as well. Though I see other standard workflow like WS76200008 etc.

Thanks
