drupal 8.1 blocks config choices different from D8 I did a migration in Nov/2015 of my D6 to D8 and the blocks look like this.


  


Then I repeated the migration of my D6 to D8 on May/2016 and my blocks 
look like this.


  


They are different.

Where is the documentation for the configuration of the block visibility

Thanks,
This is not a difference between 8.0 and 8.1, it happens in both versions.

It is a core bug, triggered by ctools. See https://www.drupal.org/node/2632434
