Good Evening all Can anyone help with a formatting issue when using checkboxes via the API?

This is the layout I’ve used in my editor:

ACTION:
I/we, having read the Joint Legal Ownership of Property Factsheet, please indicate—by ticking one of the boxes below—which option you wish to take:

[radio1|Beneficial Joint Tenants|Action1]
[radio2|Tenants in Common in equal shares|Action1]
[radio3|Other – Please Arrange a Call|Action1]

And this is how it ends up in the final issued document (formatting appears off and doesn't behave as expected).

Any advice would be appreciated!
