repeating (3 times)

Hi, I can't make the musescore play my sheet the way it should be. There is a repeat sign, which should repeat three times with three different endings.

If I set the repeating (right-click on last measure with End Repeat) to 2 (default value), the first time is played number 1, and then 2&3 (no repeating part).

If I set it to number 3, it plays first ending, then second skips, then third skips, and then plays 2nd and 3rd.

Can anyone help me? I attachted the document here (MuseScore 2.0).

Thank you
