$rowCount in ApplicationStudio Data Rule

When using application studio to modifiy Job Status Maintinace. I am duplicating a rule to follow the same process and i see $rowCount in the field and it keeps erroring out for me.

What i am trying to do is get two new custom buttons to use a duplicated rule on Job Status Maintenace and i notice Epicor is using $rowcount and I cant use that in the normal tool set as it keeps erroring out. That error below is what i got when i copied the rule

Same!

this should be what is going on if your on version 2023.2

It’s a bug that’s in development.
