The rule did not get the run time prompt automatically after click on Save button

Hello everyone,

I have one question about the run time prompt on the form.

We have a form with the rule attached to the form, and the business rule properties we choose:
Run After Save + Users Members on Form and Hide Prompt.

In the business rule, we have 4 prompt variable:
{Currency} + {Version} + {Scenario} + {Year}.

However, when users click on Save, it still shows the prompt pop-up.

Note that: On this form, we have more than 1 version.

So we would like to know if this is the system behaviour if the form has more than 1 value of prompt?

Is there any standard document about this?
