duplicate entry Mysql error when creating a paidevent node

Hello,
I am getting the following error whenever i create a paid event node.

user warning: Duplicate entry '454-2' for key 'PRIMARY' query: INSERT INTO webform_component (nid, cid, pid, form_key, name, type, value, extra, mandatory, weight) VALUES (454, 2, 0, 'uc_event_payment_status', 'Payment Status', 'select', 'unpaid', 'a:14:{s:5:\"items\";s:23:\"paid|Paid\nunpaid|Unpaid\";s:8:\"multiple\";i:0;s:7:\"private\";i:0;s:6:\"aslist\";N;s:7:\"optrand\";i:0;s:12:\"other_option\";N;s:10:\"other_text\";s:8:\"Other...\";s:13:\"title_display\";i:0;s:11:\"description\";s:0:\"\";s:11:\"custom_keys\";b:0;s:14:\"options_source\";s:0:\"\";s:21:\"conditional_component\";s:0:\"\";s:20:\"conditional_operator\";s:1:\"=\";s:18:\"conditional_values\";s:0:\"\";}', 1, 0) in /var/www/vhosts/..../httpdocs/sites/all/modules/contrib/webform/includes/webform.components.inc on line 722.

The newly created node does have the default fields in it however.

thanks.
