How to not have "-" value in choice?

[YOUNGMIN]

Hi,

I want to have my choice button exclude “-” option.

This “-” is included as a default setting.

The source of these choice options does not have “-”.

Why is this included and how can I exclude this?

Have you tried making the option a ‘required’ field rather than ‘optional’? Optional is the default setting so you get the “-“

Thanks!
