Separators mess up lay-out

Hello,

When I make use of a separator, no matter what I choose, the lay-out of the breadcrumbs are messed up, the breadcrumbs won’t show on 1 line anymore. You can see here how it looks: https://www.dropbox.com/s/v26w8wbgqbaecny/Screen%20Shot%202015-07-30%20at%2012.26.42.png?dl=0

Do you know how I can prevent this from happening?

Thanks!
