ACONT 824 Stage 2 Cooling cycles ON/Off before Setpoint Temp

My setup:

tstat: ACONT824
Outdoor unit: XL20i
Indoor unit: TAM7

I just installed the ACONT824 and wired it exactly like the diagram for 1 or 2 Stage Cooling w/TAM7 Model Variable Speed Air Handler on page 7 of the installation manual. My issue is that the Stage 2 Cooling cycles on/off before hitting the setpoint temperature (i.e. temperature is 81 and setpoint is 75). At first, I thought it was the Stage Inhibits but I disabled that by enabling Aggressive Recovery.

Comfort Settings:

Enable Dehumidification: Enabled
Smart Continuous Fan: Enabled
Control Response Rate: Normal
Aggressive Recovery: Enable

Dip Switch:

Blower OFF Delay: No Delay
Enhanced: On

Any ideas or suggestions are welcomed!

Side question, the dip switch for Airflow Mode is set to Torque. Is this correct?
