Is semantically correct have a empty legend inside a fieldset?
Hello friends, hope you're doin well! 
I'm facing a situation where I have a form structured in 3 different sections.
So my first instinct was to have a form divided into 3 fieldset, like this:
As you can see, everyone has a legend briefly describing what section is about, except the first.
I'm wondering, is correct to use the legend tag in this case, from a semantic standpoint? Or should I structure the form in a different way?
Sorry in advance if it's not quite clear, so ask further if you need more detail!
