Help re: Custodial Tax Returns for International Student

Hello everyone. I’m an international student and IDOC is requiring Custodial Tax Returns. I looked in the list of documents and there is one entitled “International Parent Non-Tax Filer Statement” which states, “This statement should be completed if you are not a U.S. citizen or eligible non-citizen and do not live in the U.S. and are not required to file a 2014* tax return in your country of residence.” My parents do however have to file tax returns in my country, and I have already uploaded their tax returns. The problem is that these documents were processed and were designated as “Other”, thus the Custodial Tax Returns item is still shown as required and un-submitted. What should I do?
