Shortcode only showing if you are logged in

Hey, when I disable this plugin I can see the contact form however when it enabled it isn't visible to the public - only if you are logged in.

Not sure why this is happening - can anyone help?

Thanks,
Mani

EDIT: Ok I see why this is happening - the option for all shortcodes to be visible is disabled. But does this mean I can't use the [free] and [paid] shortcodes to block content?

EDIT 2: I have fixed the problem by creating a new level with the ability to view that specific shortcode that was blocked.
