How can I hide pages in other locales when using Fluent?

<%- if @topic_view.topic.tags.present? %>
<%= t 'js.tagging.tags' %>: <%- @topic_view.topic.tags.each do |t| %> <%= t %> <%- end %>
<% end %>

Silverstripe Version: 4.5

Question:

I’m in the last steps of migrating a site that used to use SS 3.6 and Translatable to SS 4.5 and Fluent. Everything went fine in spite of the pain I felt going through it.

However, when I’m in the CMS backend, I see all pages in all locales despite having selected a specific locale in the filter. Instead of seeing a table of contents in en_US, for instance, I also see pages in fr_FR and pt_PT, which is overwhelming.

Is there a setting that will allow me to actually filter the site tree and not just display all pages in different colors? Thanks.
