Remove Hover State From Uploaded Submit Button

As the title says, I'm trying to figure out how to remove the hover state from an uploaded submit button graphic. I want it to do nothing at all, but it continues to show a border/background on hover despite trying multiple CSS fixes and totally starting the button over from scratch. Any thoughts?

Please try add this CSS codes on your form.

.form-submit-button.form-submit-button-img.form-submit-button-simple_white {
border : none !important;
}
