This happens because we are handling this scenario for all the other flows, but missed checklist flow.

There is also a rule bug in the mentioned form. Form element "Place of Vaccination"

statusBuilder.show().when.valueInChecklistItem("Whether Vaccination applicable").is.yes
 .or.when.valueInChecklistItem("Whether Vaccination applicable").is.undefined;

should be

statusBuilder.show().when.valueInChecklistItem("Whether Vaccination applicable").is.yes
 .or.when.valueInChecklistItem("Whether Vaccination applicable").is.notDefined;
