Problem with primary menu

Hello, i have a site with glt portfolio theme installed. Also i have installed the google translate plugin into the wordpress dashboard and i have put the languages flags into the primary menu. And now here is my problem as you can see in the site the two flags are awya from each other. I want to make the two flags to be right next to each other.

Any idea how can i do this?

Thank you very much!
