Custom role able to edit "Additional Assignment Info" section even though he shouldn't be able.

Summary:

"additional assignment info" section should not be editable.

Content (please ensure you mask any confidential information):

one of our custom roles is able to edit the "additional assignment info" section from My Client group > quick Action > Additional assignment info, despite the fact that it does not contain the role "ORA_PER_MANAGE_ADDITIONAL_ASSIGNMENT_INFO" but we only added the role "ORA_PER_VIEW_ADDITIONAL_ASSIGNMENT_INFO" to it.

Are there other privileges or roles that we need to remove from our custom role?

Thank you,

Alessandro.
