Have already linked biometrics but receive the biometrics request letter again

[Eugene Fama]

Hi,

I have submitted my biometrics information when applying for my student visa. The CIC system shows that the biometrics information is linked to my application and the biometrics is still within the expiration.

However, today I received the biometrics collection letter that asks me to collect the information. Has anybody met the same situation? What should I do?
