The label that has the dotted line under it should have a tooltip explaining 
the issue. But some of the most likely issues are:

1. DC is at 3.6 and you can't have 4.0 clusters in 3.6 DC.
2. Active host on 3.6 in the cluster. You can put the hosts in maintenance and 
upgrade the cluster, you will obviously also have to upgrade the hosts after 
that before you can activate them again.
