confirm which property you are changing from the screenshot pagelist property or work page level property.

Number of decks property it’s an embedded property of single page

@Yasvanth Tanuku

Is the rule created on the class of the single page property? Are there any when rules in the rule? Isn’t there any reference of the rule in the tracer?

Hi @Yasvanth Tanuku ,

Trace the activity after entering the data. If it is triggered and holding the value in the clipboard without populating in the section, add the action “On Change” to refresh that property.
