Trouble with List Lookup Control in Nintex Forms (New Responsive Designer)

Hi everyone,

I have added a "List Lookup" control to my Nintex Form and named it "list_lookup." I have also created a rule that always runs with some dummy logic (if "a" == "a") to add the selected value from "list_lookup" to "text_field1" in the form.

Here is what I've observed in "text_field1":

• If I select option1, option1 is visible.
• If I select option1 and then option2, only option1 is visible.
• If I select option1, deselect it, and then select option2, only option1 is visible.

I want all selected options to be visible in "text_field1." Can someone help me achieve this?

Thanks!
