Volta fail worked

I've got stuck when using the Volta. I make the same measures for repeat twice and then jump to the terza volta, I've been edited the repeat list of the prima volta and change it to "1, 2" for twice repeat and let the terza volta as a 3 but it doesn't work. When I play it, it will only one repeat and then stop. I've been looking for this problem and then I found some "Volta experiment" like what I want and it's work. He using Musescore 1 to make it and I play it on MSC 3. I tried to do the same as what he said for edit the repeat list in my own score with MSC 3 and magically it still doesn't work.
