Star Wars RPG - players unable to open modules

[Achernar22]

I have allowed the players to access the 'Star Wars Player Library'. When they open the modules button, they can see the name of the module but no book icon to allow them to open and access files.
They are able to see the 'Letter Tokens' module and open that file without any problem. I've also deleted and reinstalled the Star Wars Player Library to no avail.

When I connect to my server with localhost, I am able to see the book for the 'Star Wars Player Library' and open and access the files. But none of my players connecting remotely are able to see the book icon.

At this time I am moving everything for them (equipment, abilities, etc.) when updating characters, etc.
