Internship letter and letter from educational institution

[pbh]

I am going through CSQ process. I submitted my documents a year ago and now they asked for them again. There is one point in my application where they have asked for internship letter and a letter from educational institution stating that it was done related to my studies. I have internship letter but that was not part of educational institution but was done only for my knowledge enhancement. So i cannot provide letter from educational institution. What should I do in this case? :'(
