I think its because on your schedule search form it says
<form id="form" action="https://va.atlasgaming.group/index.php/schedules/view" method="post">
While it should be
<form id="form" action="https://va.atlasgaming.group/action.php/schedules/view" method="post">
When using index it will render the whole template and action will ony render the results part
In your php file it will probably look like
action="<?php echo url('/schedules/view')" OR action="<?php echo SITE_URL."/schedules/view" ?>"
If so it should be.
action="<?php echo actionurl('/schedules/view')"
But again I think Im saying this from memory since im at work
