<ion-label floating>Password</ion-label> not working in ionic2 rc4

Ionic Framework ionic-v3

label is not showing anymore after we upgrade ionic2 to latest and followed the steps mentioned in https://github.com/driftyco/ionic/blob/master/CHANGELOG.md for config. Are we missing any config for latest ionic2? It was working when we built 3 weeks back on fresh checkout.

here is my ionic info

FYI: It was working good. Still it works in other box which don’t have ionic2 rc4 upgrade. It is happening only after we took latest ionic2. Thanks for your support

Having both [(ngModel)] and formControlName seems strange to me. I would also try switching to the latest LTS version of node (6.9.2 last I checked).
