Anchors not erased permanently

[rainerlonau]

Using:
Unity 6 (6000.0.32.f1)
All-in-One-SDK v.71

In ColoDiscoMan.cs this part seems to execute, but the erased anchor appears again after switching to this group again. Expected behaviour: Erased anchor is gone forever.

    public static void NotifyAnchorErased(Guid uuid)
    {
        Assert.IsNotNull(s_Instance, "s_Instance should be initialized!");

        s_Instance.m_KnownAnchors.Remove(uuid);

        foreach (var group in s_Instance.m_KnownGroups.Values)
        {
            _ = group.SharedAnchors.Remove(uuid);
        }
    }
