Unable to hide withdraw action for Line Manager Learning Redwood Experience

I'm trying to hide this Withdraw action for the voluntary courses:

I have removed this roles from Line Manager custom role:

-Manage Required Learning by Learner Manager
- Manage Voluntary Learning by Learner Manager

And I have also removed all these security policies:

• manage required learning
• manage voluntary learning

But this action is still visible.

Any ideas?

Thank you for your help.

Regards,

Luca
