Unable to view policies after modifying a role in 25.1. This issue can happen on any role modification.
25.1
This is caused by the policy group mismatch that happens with the different permissions.
Workaround:
Click on server management tab and uncheck edit all.
Now go to policy tab and you should see policy groups not greyed out.
Now go back into server management tab and check edit all.
Save the role.
This issue will be addressed in a future release.
