Help With PO Needed Right Away?

I have to see my P.O. on Monday. Been on probation for 7 months for misdeminor disorderly conduct. I paid my fines & court cost, took a positive parenting cl, paid restitution, and not caused in trouble. My PO wants me to take a 40 week anger managment cl. I got a 2nd opinion from an actual Psychologist. After my evaluation he felt I had great impulse control & no need for the cl. He thought 40 weeks was ridiculous. As a result My attorney has challenged the ruling a has a hearing with the judge to challenge my PO. Can my PO arrest me on Monday when I go see her since I have refused to take the cl. I did everything legally, but my PO does not like me. Can I be arrested by her or must she go to a judge and say I am in violation to get the approval to arrest me??? I am in Columbus Ohio and need good answers. This is my life so no stupid answers please.
