After upgrading Univiewer Console to 6.8.21 or superior, if the field Label of an Alerting Rule has a blank, when updating / displaying the Alerting Rule, UVC does not display the Label so the alert cannot be modified anymore as the blanks are not authorized anymore.
Some special characters like blanks, + , - used to be accepted in the Label field.
This problem was introduced as a side-effet of a correction in version 6.8.21
