All fixed - didn’t realise the blank did not refer to the checkbox itself, but a field value in the settings. Inputting text into this field has solved the problem. 

Hi ​@CRStevens !

I'm glad you were able to resolve the issue, and that you updated this post.

Indeed, when you create a checkbox in your webform, you need to provide names for each option. To do this, simply click on the Edit Radio Options option, represented by a pencil.
