How do I delete a submit button?

I but 2 submit buttons on my form, but now can not remove one.

I have checked one of your forms and I can see the options when you click on the button are not appearing, this may be because of the template you have applied to your form or any other custom CSS code, but you can get the options also by right clicking on the button and then clicking on the delete option: 

Hope this helps.
