What rules did you get? Could you please provide the rules that you are actually setting, and the rules that the SystemRuleManager actually loaded?

That's not updated in the dashboard. Would you like to contribute?

 i fix it on my local ,but  i have no authority to push my request,how to do it

You can only create at most one SystemRule of each type. The getRules command will convert each type to individual rules.

系统规则每种只能创建一条，多条的话会以几条中的最小阈值为准。getRules API 会进行转换，每种策略转换成一条单独的规则。
