In the Role Permission Manager, why does the "Only If Creator" eliminate the Report permission?

I need both the “Only If Creator” feature and the Report feature. How can I set this up with permissions? I want users to create and view only the records from their branch, but I’m fine with them seeing reports that include records from other branches. The user permissions are currently limiting records based on the document name column, rather than any other column. How can I achieve this behavior in Frappe? I’m using Frappe version 15, not ERPNext.
