Bootstrap Views Accordion Problem
Came across your post considering I had the exact same problem. I had several different attached views to my page that were grouped by different taxonomy terms.

The way I fixed it is a little janky, but it works... basically edit the Views Bootstrap module in sites/all/modules/views_bootstrap/templates/accordion/views-bootstrap-accordion-plugin-style.tpl.php and store a random integer in PHP as a variable with rand(); then append that variable to the $key on your accordion-toggle  tag as well as the "collapse" div.

It should work after that.
