Multiline label bug

Hi!
I want to create multiline text in CocosStudio.
I use label.
For example, my text is:
"Label1 Label2 Label3 Label4 Label4 Label5 Label6 Label7 Label8 Label9 Label10 "

I set “Custom Size” for this label.
But, I see empty space below of label text (I set height as 200px)

Then, I set height as 400px

But the empty space was increased.

How I can to fix this issue?
Or, maybe, I should use other element, than a label ?

Thanks
