Can not redeclare class ...CSVBehavior

I use the CsvBehavior of ProLoser.
The Behavior is in two Table files included( TicketsTable and TestcaseTable) . Now if I include the Testcase-Table (addModel) in my ticketController, then I get the error message "can not redeclare class Cake\Model\Behavior\CsvBehavior in … on line 0"
What should I change ?
