How to remove empty field in the form?

I would also like the "third empty field" to be removed as I couldn't find the label to remove it myself. Also, when I made changes to the labels an empty field appeared and I don't seem to be able to move the next section up properly because that changes the places of the dropdown boxes:

Kindly try this custom CSS to adjust the margin in your form.

#id_48{
margin-top: -190px;
}

Please give it a try and let us know how it goes.

That works, thanks so much!
