Slidebox is not working correctly with two slides and does-continue

Using last nightly or RC4

I am using an ion-slidebox with two slides and the does-continue option.
Sometimes the pages is wrong -> i get 4 “bubbles” instead of two (after resizing).
Sometimes there are 4-dom nodes instead of 2

if i scroll backwards from the first view no pager-bubble is marked as active.

and in my codepen i can not swipe away from the last slide …

But everything is working with more than two slides

I got the issue too,any resolve?
