Comment (by FlorianBrinkmann):

 @westonruter here is the complete starter content part:
 https://gist.github.com/FlorianBrinkmann/4356ffbb8badf9604cdfbb88f09ef2df
 The entry for the post looks like that (I tried `post_name` instead
 `post_title` but this does not seem to work):

 {{{#!php
 'snowy-landscape' => [
         'post_type'  => 'post',
         'post_title' => 'Snowy Landscape',
 ],
 }}}

 I think I found the issue. The problem only appears if I use the
 customizer without a `&changeset_uuid=` in the URL (for example if I
 switched the theme via »Design« › »Themes« and not in the customizer). If
 the changeset exists, I do not get the duplicates.
