Severe errors when "migrating" jeplus job from energyplus 8.5 to 8.7

edit

Hello, upon upgrading energyplus from 8.5 to 8.7 and running a jeplus project, I received the following error.

   ** Severe  ** ZoneCapacitanceMultiplier:ResearchSpecial="1.0" invalid Zone or ZoneList Name="1.0" not found.
   ** Severe  ** GetStagedDualSetpoint: Errors with invalid names in ZoneControl:Thermostat:StagedDualSetpoint objects.
   **   ~~~   ** ...These will not be read in.  Other errors may occur.
   **  Fatal  ** Errors getting Zone Control input data.  Preceding condition(s) cause termination.

I never crerated Zone="1" and not sure whether ZoneCapacitanceMultiplier is a feature of version 8.7. Any advice?
