Difference of zone heating load reported in HVAC Sizing Summary and Coil Sizing Summary

I have a VAV with reheat system and notice that the zone heating loads reported in HVAC Sizing Summary report for Zone Sensible Heating table (e.g. 84,199Btuh) is different from the Design Size Rated Capacity in Coil:Heating:Water table , or Design Coil Load in Heating Coils table or Coil Sizing Summary Table. (these three tables all have similar loads around 66,508Btuh)

How is the Zone Sensible Heating load calculated in the HVAC Sizing Summary report? And why is it different from the loads that is used to size the terminals and reheat coils? Looks like the peak times are the same.
