[rules-users] Guvnor WS Constraints not getting activated

Hi, I tried to add field constraints to the condition and action columns in my rules. I am using a Decision table (Web guided editor) to input my rules. Even after adding the constraints I was able to save rules that violated them. I read in another post that working sets have to be activated manually. I dont see any option to do that. I am using Guvnor version 5.4.0.Final. Attaching the screenshots of the constraint and the new rule. Thanks Kannan
