Why the count of the HeaderedPump is always one in EnergyPlus?

My chilled water system contains a headeredpump:constantpump and the number of pumps in Bank is 2.But when the system work at a low load rate the pump mass flow rate is too big and the count of pump still 1. When the system work at a high load rate the count of pump is still 1.

The following is the idf and eso @MJWitte

Hard to answer without seeing the idf file. Both of the v8.3.0 example files HeaderedPumpsConSpeed.idf and HeaderedPumpsVarSpeed.idf show counts of 1 and 2 in the output.

@ndongyang Thanks for the image of the pump object, but I need the entire idf file to diagnose what is happening. Please create a helpdesk at energyplus.helpserve.com or by e-mail to energyplus-support@gard.com and attach the idf file.
