Disagg contributions from cluster sources not being computed correctly

Example: https://earthquake.usgs.gov/nshmp/hazard/disagg?commonReturnPeriods=2475&latitude=32&longitude=-92&maxDirection=false&model=CONUS_2018&returnPeriod=2475&siteClass=CD&truncate=false&disaggComponent=Total&disaggTarget=RETURN_PERIOD&imt=SA0P2&vs30=365

Select Component: SourceType: FaultCluster. Total binned contributions are 59%, but contributions in table only add up to ~43%. Something is going wrong in how cluster contributions are being computed.
