Form builder placeholders not showing

Hey, great plugin so far!

When I add a custom form and use the placeholder it shows on the form builder page, but not on the actual website.

Also is there a way to disable customer e-mail mandatory on the backend for our business to book? Or can I use a throwaway email to use when customers do not have email?

One more question. I want to change the text “Select Employee” to Select Artist or Artist. We are a tattoo shop and prefer to call our employees artists.
