[Plugin: Outerbridge Nested Shortcodes] [sd] and [/sd] visible

I just installed your nested shortcode plugin to help me fix an issue I’m having with a site I’m developing:
https://www.begenuine.com/test/colorado-listings/

I can’t seem to get rid of the [sd] and [\sd] wrapping around the password protected area. Here’s the full code:
[sd][password-protect]What happens if we put information in it’s own area, without a dropdown box for viewing? Will the sd references in brackets still appear? If so, that is a bug with the plugin..[/password-protect][/sd]
Can you help me? Will your plugin resolve this? Thanks.
