Active case stage doesn't correspond to the actual state of case instance

The following operations don't return actual information of the stages once the first stage is completed and the second stage is active:

stage = caseRuntimeDataService.getCaseInstanceStages(caseId, true, new QueryContext(0, 1));

List<CaseStage> stages = caseClient.getStages(CONTAINER_ID, caseId, true, 0, 1);
