Navigation Push from Alert

I have page with Alert popup. Once click button in alert window, it trigger navigation push another page.

It works fine if I simulate IOS from browser but using default(MD Android), the pushed page with its own header bar with back button is embedded inside tab page with header and tab from parent page. It shows odd two header bars. How can I avoid this?

This config made nav bar from parent page disappear as desired … Don’t understand why

tabSubPages: false,
