Creating single listing not working

Hi!

I just bought the plugin a while ago and wanted to try to edit the listing template. I followed the instructions here: https://plugins.yellowwave.eu/documentation/create-a-single-listing/ however, I already fail here:

You will notice that the Post Title is probably not the listing that you will want to use for designing. Click on the settings icon  in the bottom left corner. Open the Preview Settings dialog and choose for Listing, then choose which listing you want for the preview. After clicking apply and preview you should be able to see the listing in the elementor preview.

When I do that, nothing happens, I don’t see the listing in the elementor preview. What could be the cause for that?

Thanks in advance!
