Learner cannot withdraw themself from voluntary assignment initiative

Summary:

We have assigned a voluntary training via an initiative. If the learner withdraws themself from the training, the enrollment comes back after the initiative is reconciled. However, it the learning administrator withdraws them, they stay withdrawn after the reconciliation. I thought learners could withdraw themselves from voluntary assignments in all cases. Is this functioning correctly that they cannot withdraw themselves from voluntary initiatives?
