Can’t get any weather art to show

I’m unable to get any weather artwork to show in Nebula 5.0.0.

In Settings > Skin > Artwork Management > Select Weather Fanarts Artwork, I selected Weather Fanart – Multi. I tried it with and without setting the Root Folder for Custom Weather Fanarts to the folder that contains resource.images.weatherfanart.multi.

I don’t know what I’m missing. Even the weather thumbnail has the default Nebula image instead of anything weather related, even when I choose a thumbnail in the Home customization settings.
