Ionic back animation error

Ionic Framework ionic-v3
1

I’m not sure if i wrote in the correct category,

I’m building the app on an android 4.4.4 tablet and i have strange behaviour:

during a navigation pop (clicking on the back button, but happen on hardware back too)

the tags ion-title and ion-content keep some css in the style parameter that are not correct for example:
-webkit-transform: translateX(-33%);

before change page:

<ion-content padding="" class="content content-md" style="-webkit-transition: none; transition: none; opacity: 1; -webkit-transform: translateX(0%);">

then changing the page using:

this.navCtrl.push(page, {}, {animate: true, animation: 'ios-transition'}).then(
      (data) => {
        console.log("ChangePage - Open a new page: " + JSON.stringify(data));
      }
    );

and then after a back:

<ion-content padding="" class="content content-md" style="-webkit-transform: translateX(-33%); -webkit-transition: none; transition: none; opacity: 0.8;">

any idea?

Can you show a screenshot of the incorrect and incorrect state?
