Because this SWCV may imported into ESR directly via File. So you cannot find the name in SLD, because you haven't created it in SLD.
If this is an SAP standard ESR content, you cannot see it in SLD, which means the CR/CIM version of SLD too old, you need to update CR/CIM version of SLD. Then you will get all the latest SAP SWCV.
If this is a customized SWCV, you need to get the original CIM of SWCV and import into SLD.
