(or, alternatively, wrong user input method) The admin UI for the facet feature describes, that the user shall enter a comma-separated list of categories, yet a multiselection window is presented.
Interestingly, in /lib/prefs/category, where this help string comes from, is text input specified ?! If that would be presented, the text would be right, but somehow it is not...
'category_custom_facets' => [ 'name' => tr('Generate custom facets from categories'), 'description' => tr('Comma-separated list of category IDs.'), 'type' => 'text', 'size' => 15, 'filter' => 'int', 'separator' => ',', 'default' => '', 'profile_reference' => 'category', ],
