CSS Profile gives me the option to make corrections, but won't actually let me make the corrections

I made a mistake on my CSS Profile but didn’t know it was a mistake until after I’d submitted it. CSS gave me to option to make corrections, but it just opened up to an un-editable copy of my previous responses. How can I fix it? The mistake affected which IDOC documents I’m required to submit.

Unless something changed this year, you cannot make changes to a submitted Profile.

You will need to contact the colleges and ask them what you need to do.

How will this affect what you send IDOC?

Sorry if it’s too late, but anyway for anyone who wants the answer.
To correct your CSS profile you have to remove all the colleges on your list and then refresh to see the button correction.
You have to pay attention to your deadline, if you want to correct your CSS profile the night before the deadline, you may not make it in time because the college board generally takes time to I don’t know what. I mean that you won’t be able to add colleges for a while after submitting the correction. So do it early.
