1 radio-group for 2 lists of radio buttons behaves weird!?

Ionic Framework ionic-v3
1

hello,

is it possible to have 2 Lists of radio buttons but with 1 group, i tried to wrap them with a

<div radio-group>

    <ion-list >
		<ion-item>
			<ion-label>Go</ion-label>
			<ion-radio checked="true" value="go"></ion-radio>
		</ion-item>
	
		<ion-item>
			<ion-label>Python</ion-label>
			<ion-radio value="python" ></ion-radio>
		</ion-item>
	</ion-list>


    <ion-list >
		<ion-item>
			<ion-label>Go</ion-label>
			<ion-radio checked="true" value="go"></ion-radio>
		</ion-item>
	
		<ion-item>
			<ion-label>Python</ion-label>
			<ion-radio value="python" ></ion-radio>
		</ion-item>
	</ion-list>

</div>

but it has a weird behaviour, the second list of radio buttons seems to check the radio buttons on the first list!! is there a solution ?

Thank you!
