Advanced paths and Translatable slug apps

I have a new space and downloaded the translatable slugs and advanced paths apps. I also have two languages “en” and “nl”.

When I create a new story and give it an English slug called “test” and a Dutch slug of “test-nl”, then head to see the Dutch page in the editor, I am pointed to the English url in the preview pane. See image below.

How can I fix this without editing the real path of each individual story? I’m happy to edit the folder’s real path but the content editors shouldn’t have to mess with squirrely or touch the real path field when they create new stories.

Thanks for your help!
