Users don't see some contacts after deleting aggregated rawcontact because name_raw_contact_id don't change

I have a problem with NAME_RAW_CONTACT_ID in the Contacts table. The problem is users don't see some contacts after deleting aggregated rawcontact. I hope there are any ways to![enter image description here][1] solve the problem.

In /data/data/com.android.providers.contacts/databases/contacts2.db, Contacts table has NAME_RAW_CONTACT_ID field, which has rawcontactid of the contact.

The problem occurs when aggregating contacts.

When deleting the rawcontact of the aggregated contacts, occasionally the value of name_raw_contact_id is not valid. Because name_raw_contact_id hasn't been changed.

Because of this problem, Contacts table holds data, but it doensn't appear in the contacts app.

I don't see this problem on Samsung device, because name_raw_contact_id is changed automatically. However, it's not changed automatically, on LG and other devices.

To summarize, these are my questions. 1. Is there any way I can change the value of NAME_RAW_CONTACT_ID in Contacts table? 2. Is there any way to delete raw contact in RawContacts table without problem?
