WP-FAQ only displays 1 post per group

I’ve just installed this plugin on a website I’m working on. The script ran smoothly and added the numerous FAQ’s effortlessly. However, it’s only displaying 1 FAQ per group on the actual “FAQ” page where the plugin is being displayed.

Originally I thought that there was a JQuery tag somewhere in my header that was causing the script to not properly function, however when all plugins other than this one are disabled – and the theme was converted to WordPress Classic (green / white) the issue still arose.

Is there something in a function file that I’m just not finding?

I unfortunately can not provide the website itself as I’m under an NDA with the client, however I have numerous projects going on where this script would be valuable but I would like to know that it’s going to work 100% of the time.

Please help?
