CMDB/CSDM

Hi. I am currently mapping manual technical services, not using discovery. Wondering what is the correct or preferred method.  Business Service >Technical Service>Service Offering(s) (classification technical service). 

I created a manual dynamic mapped application service from the Technical Service. It shows the correct offerings with related CIs in the cmdb_rel_table.  I deleted a CI relationship and the relationship count updated correctly. There are multiple Manual Endpoint CIs in the calculated application service list even though Implement End Point to:: Implement End Point From has been filtered out of the CI relationship types. Is this normal? Is there a way to exclude these from showing when listing the Cis from the mapped application? Should the dynamic mapped application be done at the business service level?
