Why is E+ auto-sizing, oversizing the DX cooling coil?

I'm designing a DX split system for a small data center in energy plus. The calculated Design Load is 11,805 W and the program gives a coil final gross total capacity of 26,554 W. It seems like E+ is defaulting to a 610^-5 m3/sW flow rate overcapacity. When I manually input different supply airflow rates into the parent Unitary system, the capacity goes down to around 13,000 W. How do I get E+ to get a more realistic value from the auto-size function so I can iterate this simulation in JePlus?

Any input would be much appreciated!
