Sage 9 + Ultimate Member profile page

I am trying to use this plugin: https://ultimatemember.com/

I have already set up the profile page, but it is “empty”, unless I paste something into it. My partials.content-page content:

<article>
  @include('partials.page-header')

  <div class="@if (!is_account_page()) content entry-content has-margin-top-0 has-padding-bottom has-padding-top @endif">
    @php(the_content())
  </div>
</article>

I expect something like this: https://www.screencast.com/t/NJxB94A40P
Any recommendations on how to fix it?
