Records created from a record producer has empty variables values. In some cases, the variable itself is not displayed in the variable editor
London and below
The issue is caused due to the custom widget in the service portal
Users are using service portal widgets to submit the record producer.
The widget is a custom widget and the widget's submit button allows the users to click on "Submit" button multiple times.
When the "Submit" button is clicked more than once, then there will be orphan records created (along with the original record) with no variable values.
To avoid the issue, disable the Submit button as soon as it is clicked once by the user.
