Download option only works on files

I’ve passed a link to some users to test (

https://app.shade.inc/publish/194b9daa-964d-414b-a9eb-b05f6d871f88/TEST%20FOLDER%202%20-%20SHADE) and if they click on the three dots and select “download”, nothing happens. but if they go into the folder, they can download each file individually.
