Options for Radio button field to be "Yes" and "No" only

Takak Ohashi

Hello,

I have just created a new custom field with radio button. I have created two options of "Yes" and "No" but when reviewing the screen it shows "Yes", "No", and "None". I want it to show "Yes" and "No". 

There is a existing field of same configuration whose screen shows "Yes" and "No" only.

Anyone can tell what makes it show only "Yes" and "No" for the options?

 

 

Kind Regards,

You won't get the "none" option if you set a field mandatory and default it.
