In Bootstrap, when you expand or collapse accordion it just adds/removes a class "in". In the accordingly file: /templates/ja_company/acm/accordion/tmpl/style-1.php
I removed the code: '<?php if($i==0) echo 'in' ?>'
in this div tag:
<div id="collapse-<?php echo $module->id; ?><?php echo $i ?>" class="panel-collapse collapse <?php if($i==0) echo 'in' ?>" role="tabpanel" aria-labelledby="heading-<?php echo $module->id; ?><?php echo $i ?>" aria-expanded="<?php if($i==0): echo 'true'; else: echo 'false'; endif; ?>">
It should be ok now, kindly check.
