I didn't waive a right to see recommendation letters, What should i do

[rar0308]

I'm an international student.
I didn't know that not waiving the right makes the letters less effective. There was no warning sign.
I just randomly chose no and consistently did so for all my applications.
And one professor already sent a letter.

How much will this hurt my application?
Can I change this option?

You'll have to ask the places you are applying to.
