Confidential persons and merging IDs

I have merged IDs when I am confident that duplicates have been created. But I have people in n my wife's line that are now tagged as "confidential" because their place of birth is listed as Syria. Now I see duplicate persons and family groups showing up attached to other documents.

I am confident of identity because of family relationships, but merging the new ID into the "confidential" ID will hide the person and result in more duplicates. This confidential status creates a problem where none should be!
