Emerald_Lilies,
I copied your code into an empty library, commented out always_login:true, and changed the column for onlyromships to one I already had, and downloaded
those three stories.
I got 'Jaskier | Dandelion/Yennefer z Vengerbergu | Yennefer of Vengerberg' for Jarring Realities and nothing for the other two.
I believe that's what you wanted, yes? It looks like it's working to me.
Do you have a custom_columns_settings for #ships in a different section like [defaults]? You may be setting it twice.
