Collapse / Accordion "start collapsed" issue

Hi there,

I’m using your plugin for a theme based on Bootstrap 3.

All seems to be working fine except for the Accordion shortcode.

I’m unable to set it so that only the first tab is “active”. It doesn’t matter whether i set them to true, false, or leave blank they are open on page load.

Any thoughts would be great.

Thanks for your help.
Matt
