Istio virtual service doesn't work as expected

Question

i novice in istio and here is my problem. I've try'd to deploy my sample application which provide hostname of pod in minikube with istio. But something goes wrong and virtual service not working.According instructions on https://istio.io/latest/docs/setup/getting-started/ i successfully deployed my app, and when i try to apply traffic rule (90% for v1 and 10% for v2) or give all traffic for version 2, doesn't metter. It still working (50% v1 for and 50% for v2). Where i made a mistake. Here is my configuration.
