It is an issue for anyone running the latest beta. The variable in the template has changed to $schedule_list from $allroutes
2 options for now:
1 - Change the variable name supplied to the template in FrontSchedules.php
OR
2 - Create a dupllicate of the schedule_results.tpl file, name it something else, change the reference from $schedule_list to $allroutes in the template, and change the template being called in FrontSchedules.php.
