Your environment

MacOS / Chrome browser/ Stage server

Steps to reproduce

• I created a form and put a radio button component there with a few options
• I created a proper template and a workflow
• In template section I was able to see the value I selected in my template
• When I run the workflow, select an option and try to continue it says: required (for radio button)
• When the radio button is not required, I don't see the value I selected in my document.

Expected behaviour

The value I selected should reflected to my document

Same thing happens with 'checkbox' as well.
