Heap Analysis - only first value of custom event properties is tracked

    export function useHeapAddEventCaseCode(caseData?: CaseEntity) {
      return useEffect(() => {
        if (caseData?.code) {
          // As a best practice, we recommend calling clearEventProperties before addEventProperties on every page
          window.heap.clearEventProperties() 
          window.heap.addEventProperties({ caseCode: caseData.code })
        }
      }, [caseData])
    }

I'm using this effect on React SPA app in some page. Somehow it's only track first value, never see any other value even though I tried other case codes

heap array in console.log has other caseCode but none of those is sent to heap analysis or not appear
