Cant delete recurring events

Cant delete recurring events

Hi - I just signed up on zoho, 

I vreated one contact for self and entered a test appointment.   Looked at recurring screen, then closed it.  It was set at repeat none.   Zoho entered unlimited recurring appointments for test appointment for myself.  I am not asked to delete all appointments.  I can delete them  one at a time which is unproductive since there is an unlimited number of recurs.  

Am I stuck with them
