I'm a beginner.
I tried to write my CV in LaTeX and I downloaded the template from LaTeX Templates.
I used the \cvitem command but I got a problem. The margin seems too short to show all worlds in one line.
It should like this (This picture is from website):

But it looks like this:

How can I solve this problem? Should I change the moderncv template?
This is my code.
\cvitem{Date of Birth}{}
\cvitem{Place of Birth}{}
\cvitem{Gender}{Male}
\cvitem{Military Service}{}
\cvitem{Marital Status}{}
Thanks for your help.
