Multiple Repeats of Measures

I am a musescore rookie user and I use version 2.1.0. In my attached score, I want to repeat measure 4 to measure 8 four times and then skip measure 8 and jump to the measure 9. I changed the play count to 4 in measure 8 property. What I got is the measure 8 was skipped during the replay, and the sound became strange in measure 4. Could someone help me to solve the problem please. Thank you very much.
