How can I filter members by 'Visitor (set by default)' subscription

We use Membership plugin and Batch Create. In the past after adding a batch of new users I went to Membership > All Members and filtered members by 'Visitor' subscription to find all the new members. I could then check them all with one mouse click and, using Bulk Actions > Move subscription, I could move them all from 'Visitor' to the subscription they required.

Since a Membership update, new members are given 'Visitor (set by default)' subscription but this does not show in the filter (and filtering by 'Visitor' no longer reveals the new members). With a large batch of new members, it can take an hour or more to find each member and add to correct subscription one by one! Hope there is a better solution. Thanks!
