Warnings received while building for production

Bug, feature request, or proposal:

After I updated to version 7 of angular material I am receiving warnings while building for production using the command ng build --prod --build-optimizer. The warnings in the terminal are shown below

and when I deploy distribution folder to server my app is not working on the domain. It is only working in development mode at localhost:4200

What is the expected behavior?

No warnings should be there.

What is the current behavior?

Warnings are shown after build is completed using ng build --prod --build-optimizer in the terminal and the app is not working when distribution files are uploaded to hosting provider

What are the steps to reproduce?

Upgrade from angular 6 to angular 7 using https://update.angular.io

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

Angular 7, angular material 7.0.2, typescript 3.1.4

Closing as it seems this is resolved by clearing out stale node_modules
