change value to ## when condition meet

[admin]

You've probably set custom text color in element properties.
Use this CSS instead:

Code:

body.generator-off .generator-status.item-value,
body.generator-off .generator-status .value {
  color: transparent !important;  
}

body.generator-off .generator-status.item-value:before,
body.generator-off .generator-status .value:before {
  color: #000;
  content: '##';
}
