Displaying a date range with labels, what is the best practice?

So I have a date range, for example:

21-05-2022 - 27-05-2022

Bear in mind that the date is in dd-mm-yyyy format. So my user wanted to add the "Start Date" and "Due date" before the date. So it becomes like this:

Start date: 21-05-2022 - Due date: 27-05-2022

I don't think that's right, if you want to use labels I think you need to put line breaks like so:

Start date: 21-05-2022
Due date: 27-05-2022

What do you think? I need some validation for this to present to them. Thank you
