Role Hierarchy - "You can remove only roles inherited by the current role" error when try to delete

Content

Hi,

We are using 19D (11.13.19.10.0).

There is a seeded role called "Cash Manager" (Code: ORA_CE_CASH_MANAGER_JOB)

When I look at the Role, and go to edit it, when I get to step 4 (Role Hierarchy), I can see Cash Manager is also linked to the "Cash Management Administration" Roles (there are 2 - see screenshot below).

When I try to delete the roles from being linked / attached to my new role, I cannot do that, and get this error:

"You can remove only roles inherited by the current role"

I have reviewed this Oracle Doc:

Unable To Remove Roles From Customize Role (Doc ID 2235716.1)
