I suggest you take up this issue with your attorney. If the amounts are inaccurate, you may be able to have the judge reduce the amount that you pay, based on your finances.
Best of Luck.
Posting an answer to your question does not create an attorney / client relationship such that you can or should rely on the information provided herein to take action. Instead, it is intended to simply provide you with information. I am not your lawyer and cannot provide you with legal advice unless and until I am hired to do so.
You do need to consult with an attorney. Clarification may needed to be obtained from the Judge and an attorney can help you with this. You certainly don't want to wait and see if your PO will violate you.
