Eff section on position

Hello Oracle Experts

I have created a custom HR Admin Role, the idea is that this role will have access to see the positions within their data security and request changes to the existing positions, i have initially included View Positions (ORA_PER_POSITION_VIEW_DUTY) and Request a Position Change (ORA_PER_REQUEST_POSITION_CHANGE) duties and all seemed to work, however during the testing it was flagged that this role does not have access to see the position EFFs that we have created during design. i have managed to grant access to this section by including additional Maintain Positions (ORA_PER_POSITION_MAINTENANCE_DUTY) but this aggregate privilege also grants access to delete
