Multiple Voltas Playback

I am trying to get my score to play a section that has four different endings. Each time I play it, it correctly plays the first ending and jumps back to the repeat sign, and then it does the same for the second ending. However, after the second ending, when it reaches the Volta sign, it plays the second ending again, and then skips the repeat and goes into the third repeat.

Here is a textual example:

A then 1, back to A, then 2, (like normal), then it goes back to A, then 2 again, then 3, then it goes back to A and skips all the way to 4.

Here is the score:

I would really appreciate a solution! Thanks!
