Steps to Reproduce

Clear the parameterized declarative page. 

Root Cause

Resolution

1. Use the FlushDeclarativePage activity to flush data page
2. Use the below code in a Java step in a case in which all instances of the same data page across nodes must be removed:
    pega.getDeclarativePageUtils().deleteAllInstancesOfDeclarativePage("Page Name");
