Hi Kat,
Thanks for reaching out with your WeForms question and thank you for using Crio Pro WordPress theme!
I think the best thing to do in this case is edit the form itself and try removing the original submit button from the form editor.
You can also probably accomplish this with CSS. If you can link us to the form we’ll inspect it and give you our best suggestions on how to go about resolving this.
I hope this helps!
