one has a box around it and one doesn't

I can't figure out what i did differently on my two forms. One has a shadowy sort of box kind of thing and one has nothing. I chose the same way of embedding and I thought I created the forms the same way. Help please :)

This is the CSS that affect the form shadows,

1. To remove the shadow border

.supernova .form-all{
box-shadow: none;
}

2. To add the shadow border

.supernova .form-all {
    box-shadow: 0 3px 9px rgba(0, 0, 0, 0.1);
}
