Unexpected output from unpaxing CCS390 pax files. The UNZIPJCL member is missing references to relfiles.
I am facing the issue while receiving the SYSMODS for Optional and legacy components . As the UNZIPJCL provided within the package doesn't contains the entries for the RELFILES of concerned components.

After Unpaxing the received files we got the directories created as below: C14 C1401 C1401 contains the relfiles and unzip jcl for Base component, whereas the C14 contains the relfiles for MFNSM, LEGACY and OPTIONAL components but the unzip jcl is having the entries only for MFNSM component .

Could you please suggest on this whether we need to edit the JCL accordingly or you will be providing the JCL for that as well. 
The pax files should be downloaded to unique directories. The UNZIPJCL had been overlaid by the last unpax.
