Different lists in different slides scrolling at same time

I have two ionic slides, each containing a regular list.
My problem is that each time I scroll on one of them, the other scrolls at the same time.

Is there a way to make each list scroll individually?

My code somewhat like this:

 <ion-content>
  <ion-slides>
   <ion-slide>
    <ion-list>
    ...
    </ion-list>
   </ion-slide>
   <ion-slide>
    <ion-list>
    ...
    </ion-list>
   </ion-slide>
  </ion-slides>
 </ion-content>

Thank you
