Different result when the same script is run in on-demand rule vs insertion point rule on FCCS

There are some validation rules that we developed, and we noticed that the result is different between on-demand rule and configuration calculation rule.
We suspect that block is not created when the script is run within configuration calculation rule, while on-demand rule creates block automatically.

For configuration calculation rule:
FIX ("Entity Currency", "Entity Input", "Entity Consolidation")
%Script(name:="S_Validation",application:="CTFSFCCS",plantype:="Consol")
ENDFIX

For on-demand rule:
FIX("FCCS_Periodic")
%Script(name:="S_Validation",application:="CTFSFCCS",plantype:="Consol")
ENDFIX

The content in "S_Validation"

FIX("FCCS_Periodic")
FIX("FCCS_No Intercompany", "FCCS_Data Input", "No Custom1", "No Custom2", "No Custom3", "No Custom4", "FCCS_No Movement")
