Add/Edit tickets not working when i have .ics modified to categories

Hi All, since ive modified the plugin to export categories to different ics feeds following the standard useful likes inthe forum such as

http://wp-events-plugin.com/documentation/using-template-files/
http://wp-events-plugin.com/documentation/event-search-attributes/
http://wordpress.org/support/topic/plugin-events-manager-ical-feed-per-event-category?replies=20
http://srilathamarru.com/wordpress-events-manager-get-the-ical-file-per-category/
http://wordpress.org/support/topic/request-ics-export-per-category?replies=6

my tickets section does not allow me to add or edit properly, obviously a javascript problem, but since its something ive followed from the forum, imnot sure if anyone else has found a solution?
