In two separate Custom Post Types, identical slugs treated as duplicates

[likethegoddess]

Two custom post types ("Author" and "Instructors") have entries with the same title ("Joe Smith"). When creating a "Joe Smith" entry in the second CPT, the slug is appended with "-2" as if a duplicate within the same post type.

Expected result is each separate CPT entry may have identical text as a slug, as Posts and Pages may have duplicate slugs between them.
