Redis Redis cluster are not seem to good

Redis version 3.2.9

Centos 6

1. I create a redis cluster, six nodes, auto create three master nodes and three slave,then it is running not bad in a while.

2. Then I add another node to every master node,but it is confusing !! And it is changing all the time!!!
