The KB you are referring is for releases prior to CLM 4.x
This is a known Defect in CLM 4.x. It is expected to be fixed in a later patch/release.
As a workaround could you please try saving the Service Catalog without selecting the Service Blueprint. Once it is saved, edit the Service Catalog, select the Service Blueprint and save it.
Hope that helps.
How are you doing today?
As Arshad mentioned, this is a know problem and steps shared by Arshad should help you.
