I started yesterday with face recognition. How can I change the structure, that "persons" are not shown under "region". This has been done automatically by iMatch. See attached file.
The Annotation Collections (https://www.photools.com/help/imatch/#anno_basics.htm#a_col#a_col?dl=h-26) hierarchy displays all annotations you have used, grouped by their type. Face annotations are grouped under Region, and for each person a sub-collection is created automatically. This is automatic and you cannot change it. It allows you to use persons like any other smart collection, e.g. in category fomulas.
This is not the proper View to work with people. Switch to the People View to work with people in your database.
