QA Mode not showing changes as Editor does

QA Mode not showing changes as Editor does

Hi, 

I have an A/B test for mobile in draft mode. I have created the variation and I can see it is applying the changes correctly when checking using the Editor. Problem is when checking using QA mode. In QA mode the changes are not applied to the variation, even after I select the variation on the QA mode box, set the Audience Segment to mobile. 

So, since at the editor is fine, but at QA mode the changes seems to not be applied, I can't start the test because I don't know if the variation will behave properly or not.
