List not displaying after upgrade Ionic 2

Hi there

I have an existing Ionic project which I made an update to

version of
node js - v.6.9.5
npm - 4.2.0.

I updated the package.json

“dependencies”: {
"@angular/common": “2.2.1”,
"@angular/compiler": “2.2.1”,
"@angular/compiler-cli": “2.2.1”,
"@angular/core": “2.2.1”,
"@angular/forms": “2.2.1”,
"@angular/http": “2.2.1”,
"@angular/platform-browser": “2.2.1”,
"@angular/platform-browser-dynamic": “2.2.1”,
"@angular/platform-server": “2.2.1”,
"@ionic/cloud-angular": “^0.7.0”,
"@ionic/storage": “1.1.7”,
“chart.js”: “^2.3.0”,
“ionic-angular”: “2.0.0-rc.5”,
“ionic-native”: “2.2.11”,
“ionicons”: “3.0.0”,
“loadash”: “0.0.1”,
“ng2-charts”: “^1.4.1”,
“rxjs”: “5.0.0-beta.12”,
“zone.js”: “0.6.26”,
“sw-toolbox”: “3.4.0”
“devDependencies”: {
"@ionic/app-scripts": “1.0.0”,
“ng2-chartjs2”: “^1.2.0”,
“typescript”: “2.0.9”

Since I made the changes everything seems fine but onlya list of objects are not rendering anymore…specifically questions along with the answers.

This is not displaying at all…is the markup correct or am I missing something?

<ion-list text-wrap class="opl-question-container">
<ion-item *ngFor="let opl of Opls">				
	<ion-item *ngFor="let q of opl.Questions" class='questionDescibe' text-wrap>
			{{ q.QuestionName }}
		<ion-list radio-group *ngIf="q.QuestionType == 'radio'" text-wrap>
			<ion-item *ngFor="let a of q.Answers">
				<ion-label class="opl-question-answers">{{a.AnswerDescription}}</ion-label>
				<ion-radio (click)="addValue('radio',q.QuestionType, a.Correct, q.QuestionName, q.ChecboxCountCorrect, a.Answer_Id)" [value]='a.AnswerDescription'></ion-radio>
