Arkansas Tax Tables

I have a client that is upgrading to v2.19 payroll. They have one tax profile: live/work in Arkansas. Arkansas has a low income table and a regular table. Has anyone figured out how the new tax tables, which we can't see, are calculating AR tax? They have an employee that marked his AR4EC as if he is low income, but his wages don't fall into one of the categories and the AR taxes are higher than what the current system is calculating.
