Displaying additional parameters for multiple users

So I downloaded WP-Catalogue and have been editing it to my needs. The one thing I wanted was an extra field when adding items to the page, added this to the db-settings and the wp-product files and it worked great, got it to pull through to my catalogue page and single product, I have since made a new user, full admin and all, and for some reason, for this new user, the field is not visible. No errors or anything, but there was nothing user specific I set up when creating this field. Any ideas why this wouldn’t work for new users?
