Thermal Space Temperature unaffected by Sensible Cooling of VRF

Hello

I am modeling a single room that is cooled and heated by a VRF system. It has one outdoor unit and is connected to two indoor units that cool and heat the space. I have set up both units so that they begin cooling at 80 degrees F and begin to heat at 68 degrees F. The VRF system does begins cooling when the temperature goes above 80 degrees, but the rate at which the temperature increases seems to be unaffected. This is shown in the pictures below. I am unsure of why this is. Is the cooling capacity not large enough? I am fairly new to energy plus so any advice on how to trouble shoot this issue would be much appreciated.

Thank you!
