offset refund

My where's my refund updated and now it states it may partially or completely reduced to pay a past due obligation. I called the offset number and it states there is no debt owed? So i am confused. I do owe Arkansas $36.00 this year. I have student loans but haven't had to make my first payment yet not until after September.  Are they still going to take it? I dot understand what for. I am so confused. Were barley getting anything back and now they want more.
