Please fill up a webform to contact the embassy and ask them that why itsi happening ? They will give you a reason same happened with my friend and she also did same thing and just yesterday she got a mail from a embassy where she found that birthday format which an agent submitted was in yyyy/dd/mm format but required format is yyyy/mm/dd and they also asked her to provide many other related information through webmail.
So I advise you that kindly go through webform submission process and wait for their reply and if possible ask your agent also to do same.
Already did last month and still no reply til today. Im very anxious about my application cause my class starts on september 3 and I still haven't book a ticket to canada
