Is it possible delete voluntary member from an Access Group inside the topic community?

Hi to all,

we add voluntary member using an Access Group and set privacy on "Secret". Moreover we need to remove a voluntary member inside the topic community.

We removed all the member in the criteria of the Access Group and we flag the checkbox " Withdraw assignments of incomplete learners no longer a part of the learning initiative target audience" but the member stay one more time in the Access Group.

Thank you

Fabio
