"however, my income for 2024 has decreased by $8,029 while my ex-spouse's has increased by that same amount."
No, it hasn't. This does nothing to change your reportable income or your ex-spouse's reportable income. That's the reason that the judge allowed you to keep $2,294 of the $10,293. The $8,029 is being treated the same as alimony which neither you your your ex-spouse are permitted to report on a tax return.
