LoadRunner 12.53 content check issue in Controller

Hi,

I am using LoadRunner 12.53. I simply created a HTTP script and added contect check rules. Then I created a test scenario and added this script into it.  I could see the the rules when I open content check in runtime settings in controller. But once I save the scenario, close it and open it again. The content check rules are disappeared.

Does anyone has the issue?

Many thanks,

Ryan
